With the first one, I like the use of space and how it's overall simplicity complimant the piece. It doesn't need to have something in any of the empty space. The colourful lines seem a little rigid and could be altered a little to make them look a bit edgier. The text could be added to, it seems a little simple though effective. The background it cool, and it works with the graphic. Maybe you shoudl resize the pic because as I zoom out I see that there are other effects put in there that add to the work asnd make it better, such as the subtle brushing in the background.
WIth the second piece i also had to zoom out, so fuck you for not resizing.

I like the fluoro effect this one has going, and the brushing looks kinda like highlighters gone wild. I like the splatter brushing and the overall crazy colours going on, I think that is what you were aiming for. The text is pretty good, I like how it is imcomplete, and I like the brushing branching out of it in certain areas. Nice work.
8/10 for Both.
