I want to create a model for a game that looks like this side view portrait...

I just got poser 5 and am trying to figure out if I can do this by mutating the P5 male (and adding horn props) or if I need to create a custom figure (or use a program like creature lab)

I've started messing around in P5 but can't tell if it's a waste of time to keep tweaking the default figure.

any suggestions would be helpful...
