Lol, well at least after all that i learned a good bit about texturing and 3d editing, might be useful considering i like to design stuff.
Although i'd like to know, is PNG the best format for rendering on these models. or is there a better quality one i should use?

IMO yes because uncompressed, but if you're submitting to the models resource it only accepts PNG
