Awesome stuff! One thing to keep note of for your work is antialiasing - keeping the edges of your Pokemon smooth. The Azumarill on the rocks has pixellated edges, detracting from its quality. You can fix that in multiple ways; my ways are either (1) put effort into increasing the antialiasing quality in your 3D rendering software or (2) blending the render with the background with eagle-eye precision in your image editing software. This sort of thing is very noticeable on both of your Azumarill renders - Donphan and Starmie look perfect, so I'm thinking you might have picked up on the AA stuff already. Keep up the good work!
