Hey Everyone!
This is my first post here, was referred by a friend and have been looking around for a bit. Seems like a really nice userbase and good critiques without shooting the person to smithereens too much.

I'm doing a Bachelor of Games Design at Uni, currently first year. For our current programming assignment we need to make a game that has three levels in it.
For some reason; three weeks before the thing is due (also before i've actually nailed down any gameplay code) I decided to make the tiles for my game as pixel art~!
I'm happy to admit I am not much chop as an artist; and this is the first time I've ever tried anything pixel-art-esque.
I was wondering if you have any hints/tips/pointers on how I can improve these tiles and my pixelart in general, as I actually had a lot of fun doing it!


Hope you guys can help. Would be much appreciated!
Thanks in advance!
