Am nervous and pleased to announce that I have made a Ko-Fi! You can give me a tip and/or make an art request there.
For a minimum of $2 I will draw a headshot (at least) of a pokemon of your choosing, or I'll doodle up a galaxy piece in the colours and style you choose. You can see the full details on the intro post of my page (hopefully).
I'm just testing this out, so we'll see how it goes! Things may change as I learn and adjust.
If you like the existing galaxy designs, you can get them on my redbubble!
