Many years ago, I created these drawings with the help of an art program. It basically simulates art tools and you do the work of drawing and coloring. I did Megaman 2 because I loved that game on NES.
I never really cared for Metal Gear on NES, but I did one for the heck of it.
I also did some box-arts as well, I loved the iconic one for Super Mario World. In retrospect it does look a bit rough.
I consider my magnum opus so far to be my Pokemon Blue artwork. In my not so humble opinion besides some text that got blurry on the bottom (mostly the program's fault for size issues) I got this one near-perfect. Fitting for my ode to the game that presented me my childhood in one plastic cartridge.
