We'd have to see a flare picture to really be able to critique him but this is what I see for now:
He's a DT so you should be able to see the split clearly but he's got too much finnage to see it. His first few rays on his dorsal are stubby which is common on DT's but still a fault. Ventral fins are nice long and full. Lobes of the tail don't look proportionate and the fins meet up top but not on the bottom; caudal to anal fin. As for color he's an extremely mess tri-color. He could almost be a butterfly if that light blue went all the way around but it doesn't so therefore; messy
Body looks nice and long though, doesn't seem to have a crooked spine like most DT's, a bit spoon headed but otherwise not too bad.
