good use of reference, and great clean concepts, i too recommend human face and boobs. Bias i guess. Also, although i like making crazy monsters as much as anyone, port pieces are better if they have some trace of human anatomy in them.
lol wut *edit - i'll clarify. I think this advice is arbitrary and is not fitting here. While yes, a well made human character will often stand out in a portfolio, I don't think adding human anatomy onto your monster for no reason other than this will elevate it in any meaningful way. I would rather see someone competently…
