looks great, Cyangmou out of curiosity, how do you choose what to draw? you went from humans to horses, then humans, and now dinosaurs.
I am studying the
design of the things I like. Last year I also did some armor, architectural and machine studies.
While humans are important for multiple easy explainable reasons, the other things have to do with personal preferences and interests.
btw: IMO the abdomen wouldn't ever have a sharp square edge there were you drew one in. If it's exactly like that in the photo I'd be really curious to see your reference.
