A Pixelated Drawing of An Astronaut

So far so good this is the best work I have ever done, I don't know what brought thus idea my way but it should keep coming. Now I should say I qualified to be called an Artist who specializes on Pixelated drawings and a day would come when I would be called an Artist who specializes on all forms of art. For now this is the only art I can do and some cute Cinderella drawings.
Just to let you know my little brother didn't assist in this idea, it was fully mine.
Most people call me a fast learner and I'm seeing signs that its true, day one I was shaking while drawing and day four I am already doing things I don't expect.
