Wow, that's a different idea as opposed to the drawings... pixel art's gonna get a lot of requests from you. ;) Way more than what you've got now, especially since you're so good at it.
As an "In Memory Of" sort of thing, I'd like you to do one of my girl Leliia, if you would be so kind.
Her true colors are best shown in this first picture.
She was a Halfmoon/Plakat dragon. My first betta after a long time being away from fish... first girl too. Her birthday's in January, so yeah, I think it'd make a neat thing to add in my signature. <3
