The renders look good and the lightning of the renders also greatly depend on the scene as if it’s outside in the sun make it a bit bright and if inside house do it accordingly. Lighting plays an important role and you should also work on making some backgrounds too. Anyways, good effort.
I’ll cut straight to the point, as I agree with what others have said regarding the render and the background.
The render itself is to a good standard, yet the backgrounds let it down as a piece overall. If possible, hop into Roblox Studio and get a scene you’d like as the background of the GFX. From there, you can take a screenshot of some sort, as some extra detailing - such as a sun flare - and add it to the necessary layer.
Thank you all for the feedback! It’s super helpful. Regarding backgrounds and lighting and stuff, I’ll try to better them. I’m pretty new to making edits to my work and backgrounds, because I’m used to just doing plain color backgrounds. Your guys’ help is amazing and I appreciate it!
I’d say that yes, you are ready to charge, but not for very much. For the 2nd image, the background is really distracting, I think it would be best if you blurred the background a bit and changed the colors slightly to be more soft and match the character more.
