RE: safariblade designs (critique for 'music is primary')
The paper you used works with this piece. The purple plays off the yellow. (complementary color) which makes it pretty visually interesting. You also did a good job on the arrangement of the tapes, because it goes in order with the color wheel. The frame around the piece does a pretty good job of leading the eye through it as well, because it touches the cassette tapes in two spots. If I had any suggestions, a diagonal placement of the cassettes might have been a good alternative to this. I also should say that turning the cassettes upside down looks pretty good, more interesting than right side up. For the medium, spray paint is hard to get right on plastic, but it doesn't look too bad. You can see the texture, not sure if it was intentional or not. If you wanted more of a smooth look, might consider layers of primer + sanding next time to smooth it out when working with a texture.
Overall, I give it a 7/10.
