Hi Daniel,
the model looks really promising - the head detail looks really good and is proportioned nicely. May I make an observation on the whole body image though? The legs seem a little long in respect the rest of the body, perhaps shortening them a little may help.
Keep it up though, look forward to seeing how the model develops!
You're far braver than I am though - I certainly wouldn't tackle characher modelling unless I really had to!
Cheers
Steve
