You managed to make such a masterpiece with the Spinosaurus that has good looks before the new, but more scientifically accurate discoveries come along. the stripes bring out the blue tiger intimidation. The Crest is merely a sign of a dangerous approach with other predators. Even the underbelly and claws are also very well designed.
The Spinosaurus is the king of the swamps of Africa until the Chacarodontasaurus entered into the fray, causing their extinction.
Anyways, good job on the sail. It has been shown that it no longer was considered a sail, but a structure of bones in it's spine.
