Have you ever sprited before, talha? Or are you starting from the absolute basics? Pop into the FEU Discord and have a chat with the lead spriters. AFAIK, Circles started off spriting at the absolute basics not even three years ago and now he's one of the better battle spriters in the community. People like him can give you all sorts of help, as well as teach you how to actually format stuff for insertion.
