I find that having an image in front of you of a mudokon really helps, the Art of OWI is invaluable.
This is the first one I did that came out well. You'll find that drawing them makes you more aware of little details. Copy them out first, before you start drawing them from scratch (which is still beyond me).
If you have access to a scanner and Photoshop, then colouring them gets easier. Mess with the image's light/darkness and contrast untill it looks good on the screen, and then get a lassoo around the outline of the mudokon. Copy that onto a new layer and set the layer to multiply, and apply colour on the layer below. Multiply makes the white spaces appear the colour on the layers beyow, and the grey areas become shaded colours.
The dodge brush (set to highlights) allows you to make areas brighter, like the light is shining on the mudokon. The burn tool (also set to highlights) creates shadows.
This is Kobe after colouring. I used smart blur on the sketch layer to blend the pencil marks.
Drawing them in different positions is easier with a mannequin. I don't have one so I used pictures of other humanoids to get the positions right, but change them to mudokons. That is how I was able to complete this
