3D render of the clay Azumarill seemed rather real at first glance haha. Great job with it!
Considering this is the Smeargle's Canvas forum, I would like to redirect you over to Imposter Professor Oak's Fakes forum. That forum is where faking materials can be posted, so if you have fake cards you would like to show to the community, it would be better if you could create a thread there, since the forum is reserved for posting fan-made materials (cards, full tcg sets, games, fakemon, etc). You would use this thread to continue showing off your 3D renders of Pokemon or any other type of non-fake related artwork. Hope that makes sense!
Anyways, I really, really like your Azumarill render! It doesn't feel like a sticker placed over a model like those I've tried to render, but instead has proper shading and the like. It also looks perfect for a card!
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!
