Hi there, I'm no artist and I'm very new to pixel art.
I'm actually a c++ developer making a game and I'm in love with pixel art. Here's my attempt to make the combat screen at 800x600.

The ships and space tile are not mine, I bought them here (http://graphicriver.net/item/space-shooter-objects/142231), I hope this is not a problem.

I'm using DawnBringer 16 Color Palette and I'm using this pieces as inspiration:

I'm going to add more details later, like there's only two ship components being shown there.

I know there's a lot to improve but at my limit here.
Anyway, thanks for your time reading this.

Thanks.
Actually this is the minimum size since it's a pc game.
