Hey, I used to use JASC Paint Shop Pro/Animation Shop too and they were pretty great for pixel art back... 15 years ago, was it? Asprite is great, but let me also put in a vote for Cosmigo Pro Motion, it's been my tool of the trade for a long time, if you like Deluxe Paint and understand that workflow, it'll feel natural. If not, it has a bit of a learning curve.
