Danny's crappy book of sketches

[Samszym]

Nice effort! Looks to me like you're drawing the features too soon in those heads, try building them up in simple forms before you draw any of the things that you recognize as a face. Make a sphere with sides chopped off for the cranium, a block to locate the nose, a cylinder to locate the mouth, etc. Nail those simplified forms, then move on to details! If you get the features of the skull and construction right you'll have already drawn an awesome head before even thinking of the eyelashes or nostrils.

Continue to rock!!!
