At last I did some paleo art that isn't dinosaurs

Glyptodontids are awesome, but I hate drawing them because of their carapaces. The scutes should have various shapes, as can be seen here
[link] , but all I can draw is circles

Glyptodontids appeared in the Miocene and went extinct in the Pleistocene.
The animals below are
synapsids, from the Permian epoch.
Titanophoneus here has some hair-like stuff, I have no idea whether it's correct or not.
Heck, those are MASTERPIECES, not mere sketches, i tell ya!
If only i had half of your talent, man...
That said, interesting details to the Titanophoneus. It's interesting to see how different people depict the dermal characteristics of synapsids.
