I kind of like where you are taking it, in a way that kind of focuses on a particular part of the dolphin, but it looks like a shark and you can't hide from that. It is clean though, kind of aggressive but it really looks better not on the helmet. when you put it on the helmet it doesn't look right. what i think you should try is the same concept of a fragment of the dolphin, but try the head with white orange and teal or the tail. also, you know that sun graphic, what if it was down the center of the helmet? how would that look coming down and around the helmet? idk if that looks good or not but i wouldn't mind seeing what it would look like.
