Hey friends,
I mostly work in vectors but as I love retro and indie games I decides to try pixel art. I'm having a lot of fun.
Thanks for checking my stuff. :)
I'm guessing the blurriness is to do with the scaling technique that you're using within your image editor. If you can switch it to "Nearest Neighbour", the pixels should remain sharp. I'm sure that if you google your editing software and use the terms "scale" or "Transform" with the term "Nearest Neighbour", you'll find how to do it pretty quick.
Very nice work. :)
