here's the link I put up before https://www.xyzrgb.com/maps/skins/index.html
I bought some of the maps here and used them as the starting point for the displacement map. I also used gray scale images of cracked desert and elephant skin and put them all to gether in photoshop.
He dosen't exist in a real low poly mode because I modeled his bones and muscles first and than modeled the skin to fit around them. Here he is in wireframe.
Yeah his paws in the back legs are smaller than a dinosaur but he has four of them instead of two. I also made his upper body and tail the same size in relation to his back leegs as a t-rex plus his tail acts as a huge counter weight and his arm muscles are large. He might also look different depending on the length of the lense.
