Check rounded lobes, sinuses and continuous blade tissue without turning side veins into a compound-leaf branch.

An English oak leaf can mistakenly become separate leaflets hung along a stem. Use Quercus robur as the structural reference for an invented pose and colours in Aquarell. Distinguish one blade, rounded lobes and branching veins without generalising to every oak or identifying collected plants from an invented illustration.

## Block one complete leaf blade

Use an approximately 1500×1700 px portrait canvas, cream background and short petiole from lower-left toward upper-right. Establish midrib and length/width envelope before placing repeated ovals. Tip and base belong to one blade. Separate sketch, blade, veins, shade and checks in mid-green. Broaden a feather-like shape and establish one base if two leaves seem paired. Canvas size and orientation are invented, not centimetres or evidence that natural individual variation is a software fault.

## Form rounded lobes from the blade edge

Arrange several rounded lobes and intervening sinuses along both edges, without strict mirror symmetry or a universal lobe count. Retain blade tissue connecting lobes around the midrib; sinuses must not sever them into leaflets. Check a flat silhouette before texture and repair serrations or spikes. Replace maple-like palmately radiating points with lobes distributed along the midrib, and join grape-like isolated circles with tissue. Rounded lobes and a short petiole are reference cues, not an invented precise sinus-depth ratio or cultivar identification.

## Run side veins from the midrib into lobes

Extend one midrib from petiole to tip, branching side veins at different positions into the lobes and thinning them outward. Do not radiate every vein from the base or place a thick branch at each sinus. Keep a few clear veins and omit fine reticulation if necessary. Reduce overly woody veins and reconnect tissue if branch-with-leaves-like; re-establish one axis if ginkgo-fan-like. Veins follow this curved blade without exposing every hidden underside vein or claiming a measured vein count.

## Join the short petiole to the blade base

Continue the petiole from the midrib base. Rounded basal ears may appear, without exaggerating them into extra leaflets. Do not attach the stalk to a side-lobe tip or introduce a long branch to explain every join. Hide side veins and check the blade-to-petiole transition before a tiny contact shadow. Repair a bow-tie-like base through blade convergence rather than binding cord. This is one leaf, not a whole plant; infer no leaf arrangement, flowers or acorn stalks. Any added twig is another organ level, not the petiole.

## Carry shading across one blade

Light from upper-left, with modest midrib relief and corresponding lobe shading, not separate spheres. Establish one broad tonal passage across the blade before local curled-edge shade. Sinuses expose background rather than black interior cracks. Reduce isolated lobe glints if fleshy-petal-like and recover the unified plane. Veins may be lighter without white engraving, and both sides share illumination. Greens describe volume, not diagnosed nutrition, disease or season. Omit unreferenced natural blemishes.

## Check each sinus as background negative space

Temporarily use a grey checking background and trace the entire edge, confirming continuous lobes and sinuses. Deep sinuses still leave tissue; background gaps must not reach the midrib and continue across it. Vary size/curvature if gear-like without adding random holes for naturalness. Restore cream and recover a lost petiole locally rather than outlining the leaf in black. Use a copy or temporary display, preserving the original background and not presenting checking colours as natural foliage or habitat.

## Troubleshoot single-versus-compound-leaf confusion

At roughly quarter size, ignore the title and ask whether one continuous blade reads. Reconnect tissue, soften thick side veins and remove invented individual lobe stalks if compound-leaf-like. Establish one midrib and base-to-tip direction if flower-fan-like instead of adding explanatory labels. Hide full-envelope and symmetry guides while retaining visible asymmetry. Keep the English oak reference rather than mixing another oak’s pointed lobes or spiny edges into a claim about all oaks. Unknown plants need separate reliable references.

## Reopen the export and recheck blade continuity

Save the layered native artwork, export PNG and reopen it. Check the short basal petiole, continuous midrib, rounded lobes and sinuses that do not sever the blade. Repair merging gaps through local spacing or scale instead of uniform serrations. Weaken branch-like veins in the source rather than blurring the entire shared image. Record the English oak type, invented pose and omitted fine veins/twig/fruit. Success concerns a coherent single blade, negative space and venation, not species identification from a drawn lobe count.
