good colors but you need to smooth the dragons back or make it look like his elbow, rework the guys feet and the rock he is on... it looks like a strange puddle of water and he seems to be on his toes but his arm isn't fully extended, people only stand on their toes when their arms don't reach far enough. Oh and its not obvious enough that its marshmallows, if anything they should be dark and on burnt, as if they were on fire. Just a simple crit, hope it helps
