I'm not one that looks at space art much, but I love abstract art, so I've seen a ton of it. This is actually the first peice of Spae Art I've ever seen that I have actually made my wall paper before. I usually pass by it. I honestly see no flaws, but IMO, I'd like to see more open, black space. Too much BRIGHT COLORS for me. I loke my abstract art to be dark, with subtle strokes of color here and there.
Still an amazing piece that I absolutely love. Keep it up bro, you could go far.
