Very nice looking so far. Also I feel like the scorpion tail mutants would look better with some horns or spikes coming out of his skull hat as to me it just looks a little weird the way the skull is on his head with the way hes looking down. The spines guy looks like he needs some more spikes coming out. My only other suggestion on the mutants would be to give them some more junk
hanging off them. Backpacks, pouches fish etc.
