Rideable Spinosaurus

This is my attempt at creating a game ready Spinosaurus as part of a University module. The project was sculpted in Zbrush, retopped and unwrapped in Maya, textured in substance painter and then presented in Unreal Engine.
The colours were based on that of the Marine Iguana, a lizard that lives both on land and feeds in the water.

Any feedback on where to improve is welcome !
