Hi Thiago,
I'm currently developing a 2D Sidescrolling RPG and I'm in need of quite a lot of Pixel Art pieces such as Tilesets, Mob Sprites, Items, etc.
Do you have any more work you could show me, a portfolio/deviantart page or something similar, as I would be quite interested in asking you to join me on the project.
You can see the current progress
here.
I'm looking for artwork similar to that in games like Terraria, Starbound and Magicite.
If you're interested please let me know and we can have a chat!
Cheers,
Andy.
