1. Line drawings - (I thought of the three poses on the left first and based the right most one off of them).
2. Adding local color - Started to add color on a Multiply layer to figure out the composition. It is great if I have the anatomy figured out at this stage, but the gesture is what's most important.
3. Build a library of reference images - At this point (or even before) I grab photo reference from the internet and have it scattered around my photoshop document. Not all of them will be useful, but it's helpful to have a lot in case you need to change direction.
4. Then the next steps are just continue to refine and add paint. I might make a gif of one of the witchies, stay tuned :)
