Hello and welcome, to my new sprite shop! I'm fairly new to the spriting business, although I like to think I'm better at banners. Here's what I have to offer...
Simple, really. For a palette swap, list the Pokemon, and the Pokemon you want to swap palettes with. Or, you can request an alternate coloration. Or, there's my specialty, Corrupted Pokemon. A Dark purple and blood-red coloration.
All banners will have the standard size of 150 x 450 unless stated otherwise. Simply describe the banner you want, including things such as text, images, and the background.
Same deal, describe the avatar you want.
Okay, a disclaimer here. I'm not the best when it comes to these. Try not to request splices of overly complicated Pokemon, and understand that your request may be beyond my capabilities.
