thanks alot guys for the comments, work took me like 6months and some extra time while learning mari.
most of my references where tortoises and monitor lizards for the texture i started with basic colors and picked a palette i liked before detail then looked for animals i liked to match the way their scales or plates look all the texturing is hand made no use of any kind of texture only mask to create dirt, baked outside mari cavity ao curvature maps ect
thanks again!
