Delphin - The Water Baby

Personal Info

Personality: What a dragon this little one is turning out to be! He is full of fun and happiness, and loves a good laugh. Delph is very responsible, and cares for his sisters like no other. He can get angry too, his temper roaring like the dangerous waves far out to sea, but he can be tranquil, and calm like the waves lapping at the sands of his home. A naturally inquisitive dragon, Delphin is perfect for what he is training to become, a tracker. He hopes he can become a leader in years to come, then maybe a God!

Background
History:
RP Sample: The sea water lapped at Delphin ankles. Eight fast years had past since his birth, and he had begun his training. Boy, was it difficult. The chattering of sea-creatures was in his ears, still something he hadn't  quite perfected was shutting their noise out. Anyway. A roar escaped his jaws. Decent, but, let's try again. He repeated, until it had reached it's perfect sound. Loud and deep. It reverberated across the cliffs around him, and loose pebbles fell. Again and again he roared that day, until it was perfect.

Looks alright to me, apart from the the adult size, which I would say something like 25-32ft since Ark is only 32ft and Ocean around the same.

Other than that APPROVED

p.s Make sure to add more later on, since you will get older.
