Hi,new alien concept .
Very nice. Really like the colour scheme. The spikes on his jaw?/chin? look like they should be a subtool and a bit more definition even it its just a tip of a spike sticking out of the flesh. Maybe you don’t intend them to be horns/teeth but they colouring makes them look that way to me.
Thank you DrApple,yes, I should make different SubTool (sorry for my english)
