I think I found a good replacement for photoshop called clip paint studio. I just bought it and it's only $50 (price may vary). I was still using photoshop 6 lol but it couldn't open the most recent PSD files artists sent me. Now with this little program I can do it
cool, not being an artist I can't judge that well but I've checked some videos and indeed seems very powerful. For sure it's enough for all my needs for now
