Wrestling Ring (One year later)

Howdy, it’s been a year since my last post here, I’ve been very busy not knowing what I would do for university and felt my previous artwork wasn’t good enough so I took some time off from pixel art. But after some time a came back to improve my skill and have been working on some stuff, I still feel I can improve this, so if you have any tips on where I can improve please let me know!
