This is a single cover I made for a song that I just posted to SoundCloud:

Made using pixilart.com

I'm still pretty new to pixel art, but as I've gotten more comfortable, I've been challenging myself by increasing the image's pixel count. This one is 128x128, or the same size as a small Minecraft map for reference.

When I started drawing, it seemed really hard, and I was a bit discouraged. But I kept going, and after gradually working on this for a couple of weeks, I am super happy with how it turned out!
