Redwall Otter 3D Model

Ehy guys, I decided to give a try to a character not completely human just to challenge myself.
I found this lovely Redwall Otter concept in Pinterest and I just loved it! I hope to have been able to give it justice.
As always critique and suggestions are welcome.

Model sculpted in Zbrush, Retopologized in Maya, Baked in Marmoset, Textured in Substance Painter and Posed in Zbrush.
Render made in Marmoset and Unreal. The Background in unreal is made using the Advanced Village Pack from the Unreal Marketplace.
