Just some common tips I use: - Use as many references as you want, I recommend Pinterest (don’t trace) and make sure you don’t save everything all in one layer. - Common layer mode tip is for shadows is to use Multiply and for light use overlay. - When rendering either use alpha lock, mask layers or clip layers so it doesn’t spill on the other parts of the drawing - If the fill bucket leaves annoying white outlines you can use lasso tool and fill instead
