Single post in Sprite Permission Request Thread

Hi! I'm a little confused with the rules, and was hoping to edit a few different sprites, starting with a basic Larvitar so it looks like a friend of mines pokemon (as far as I know, they do not have a pokefarm account), as well as others based on my friends in the future (that I'll ask when the times comes of course!). So, I was basically wondering how the sprites work, like are they only for 'about me's, or would we be able to customize the sprites on the physical farm? Thank you for reading (and I apologize for this being so long)!
