Still working on it and I do not think it would be something great. But I enjoy it:). I welcome criticism.

Edit: I must retopologize this. Wire is horrible :(.
Second version with details 
Thumbnail links gives only error page.
hm very deep groove under sternum even that i saw it on a real modell on the sternum region itself which was also strange and collar bone/clavis looks too short or just unusual.
Thnaks for comment. Its stylized woman body like manga. I will try it better ;).
for your first model that looks pretty cool! I like that style and I’m currently trialing with the same task (final fantasy style). Can you show the topology?
