Use a sketch to guide an anime AI concept.

Use your own drawing or one you have permission to process. Crop away unrelated notes, page edges, and private details. Preserve enough space around the subject that the model can understand the pose.

Darken the lines that define the silhouette and major costume shapes. Remove abandoned limbs or overlapping pose studies from the same source. If two arm positions remain visible, the model may interpret both as part of the character.

A rough sketch can be useful without being polished. The important question is whether a viewer can distinguish the figure, clothing, and intended action. Fix ambiguity that would also confuse a human collaborator.

Separate the design into fixed and flexible decisions. You might require a mature face, a long coat, and a left-facing pose while allowing the model to explore fabric texture and lighting.

Proposed brief for a clothed adult sketch: “Develop this original adult traveler concept into an anime illustration. Preserve the long coat silhouette, left-facing stance, and single shoulder bag. Use muted earth colors and a simple background.” This example describes intent, not measured model behavior.

Do not ask for a radically different pose while also demanding exact preservation of the sketch. Choose whether you are refining the drawing or using it as loose inspiration. That decision should guide the amount of change you accept.

Use the source and one short prompt with the selected model’s available controls. Compare a limited number of supported strength options while keeping the other inputs steady. Avoid importing numeric settings from an unrelated tool.

Inspect silhouette, limb placement, costume edges, and the bag attachment before judging texture. If the image looks polished but drops the defining coat shape, it failed a fixed part of the brief.

Record the chosen control, model, and source version beside each candidate. Save the sketch itself; a screenshot of the result does not preserve the input needed to explain a later change.

If the model keeps turning a fold into a strap, look at the source drawing. The line may have too much visual weight or may connect in a way that suggests a separate object. Editing that line can be more useful than adding another negative term.

If the hand is unclear, redraw a simpler gesture or use a permitted reference to clarify it. A refinement pass cannot infer every hidden construction decision. You may need to solve the pose before asking for a finished surface.

Keep a before-and-after copy of the source revision. This lets you tell whether improving the drawing helped, without inventing a success percentage from one selected result.

For concept exploration, a partly reinterpreted image may be useful. For a commissioned design, exact markings and construction may need manual correction. Agree on that distinction with the next artist before presenting the output as final.

Some services offer image-guidance modes for different tasks. Leonardo’s documentation is a useful example of why the role of a reference matters. Its named controls are not instructions for Lewdora; use the compatible workflow in the product you have selected.

Export the accepted concept with the original sketch and a list of intentional changes. Keep AI-use and reference-permission notes with the project. Lewdora creates a still image, not editable vector paths or a layered reconstruction of your drawing.
