So, this is made with Paint..?
Dude, do yourself a favor and download
GIMP. If you got some cash to spare, buy
SAI Paint Tool. Download the
Photoshop trial version and see what you think about it, if you have the cash, buy it; else I'd get it in a more... Shady way.
You got the talent; don't limit yourself with MS Paint. It's almost like limiting yourself to only draw on cardboard with crayons; use the tools available to you, especially if some of them are free.
I can agree that MS Paint gives a certain esthetic feel, but please... Don't limit yourself to it when you got the talent to do so much more than this pixelated art; I’m already looking forward to see how much your art will evolve over the next couple of years if you choose stick around.
