Hi guys... So, I'm working on a game I made with a few guys on a game jam and I need to improve my backgrounds and tileset. I'm still new to pixel art and stuff so I need a few tips on how to improve this stuff.

(In game there is some parallax going on with these layers)



(Couldn't find the original on this one so I printed it from my portfolio page... I'm not with my computer right now)




And here is a preview on how the first BG looks in game, with the tileset I made

(It's a screenshot from the game on the browser)
Disclaimer: I didn't make the characters nor the chains.
