I'm very new to this, and I've never made an edited sprite, but I'd like to share the sprites I do make. I'll be sure to update this after I've made a new sprite or an edit.
Gym Leader Edits:
Erika's hair was edited, and there was a significant recolour. Colours were mostly taken from Misty and Janine. She looks a little pink, but that's only cause when I saved it, wt went strange and..really messed it up.
Misty's jacket and eyes was re-coloured, but the band in her hair was taken from Shaymin's Sky Form. Colours taken from Jirachi. I also decided to animate this, just as a test.
Separate frames were found on Project Pokémon.
