Frankly I don't think I would really change a lot, mostly just some design choices and I tapped a bit more in the raptor with the feet
I'll also add my character so the chain can continue. I've actually been meaning to give him a new outfit for chapter 5 and onward so maybe this will be helpful:
This is Akros, he is a 23 year old traveler. He was enslaved and had to do child labour in his youth. He eventually managed to escape and from that point onwards he kept traveling, cultivating his one power to manipulate the earth and rock around him. He is a serious and stoic individual most of the time. He is also bad at cooking.
