Noo. This animal needs far more details!
When ArcaneFalcon gives the rhino as reference this is good. Willen drawing is not detailed at all, it\'s just a four leg thing with a shield on the head.
If you want to make it in 3D you must show and emphasize all the muscles, and such beast probably have a ton.
The head is not detailed at all, not the eye hollow, the jaw definition is wrong and you could give a better throat shape.
The mouth is linear, like the nature took a cutter and made a clean horizontal cut for this mouth (without any tooth).
Keep working on it, don\'t give up that easily!! :p
