Amazing work, thank you for sharing!
I can see the Disney inspiration in that crocodile, he reminds me a little bit of the crocodile from The Princess and the Frog. This one looks a lot meaner and hungrier though. ;)
The skull is also amazing, I really love your shading!
Thank you so much! Yes I am very influenced by Disney in my drawing - and Louis from The Princess and the Frog was most certainly a ref for this guy :D
