Hey Xerges - The comical tone of the model and his animations are pretty nice.
Here are a couple suggestions I think might increase the quality of the model resulting in a better product for customers which could result in more purchases.
The still images on the asset store page do nothing to show the model in the best light. Honestly I think the lighting is not very good and the lack of a proper shader causes the overly high poly model to look not as good as it should.
I’d be scared to ask to see a wireframe for the model because the polygon count is approximately triple what a simple model like this should be. A good number to shoot for is around 1000 polygons. With a nice shader and proper supporting maps, normal, spec, gloss etc - this model would be better optimized and look just as good if not better than it currently does.
Modeling the nostril holes for the pig should also be added to the model simply because it’s such a prominent aspect of the model.
The animations are comical and look pretty good. I think showing the attack animation and adding an alternate attack as well as a death cycle would be very useful for anybody looking to purchase this pack. A lay down and get up would also probably be nice animations to add.
Adding some detail where the hoves start on the leg would probably add a little character to the model. Maybe making them a little bigger.
I also think the model is slightly over priced, but that is your own personal decision. With the changes suggested it might be worth the price you are asking for.
I hope you see this as constructive feedback and not discouraging to your art. With the modifications incorporated this model could be used for a lot more genres than the two you mentioned.
