I'm obviously going to sound assey saying this but that's not your artwork and you can't really brag when all you did was trace a 12x16 image.
Just going on a bit of a rant here, but "pixel art" is the completely wrong term for these things due to the fact that pixels are what an image consists of and isn't restricted to a small resolution image. What I find even more annoying is the fact that people use that "ooh, it's pixel art" as an excuse to have mind-bogglingly small image canvases so they are permitted to completely disregard any kind of effort whatsoever.
