DRAGON PAINTINGS
1 Start from a sketch
Once you have found the right sketch to develop, start by cleaning the lineart on a separate layer, decide the light source and then create a new layer for the main shadows.
2 New layers
Next up, create a new layer for the flat colours, and if the shadows work you can turn the shadow layer to Multiply. You can also enhance the colour with a new overlay layer.
3 Refine the details
Create a copy of the layers used so far and flatten them. At this point you can begin to paint and refine the details. Remember not to focus on a single area, but focus on the whole piece.
