uh....worked on it a while ago and decided to edit it and redo it. Dusk Purple and Kelly Green!

Why is there a panda?

I like your other design too. The rawness of the thick lines contrasting the thin ones and keeping your notes in tact is I think very cool. In this the two background forms occupy the same space and that doesn't quite work, but my main suggestion is that you might try to incorporate some architectural, geometric forms. For example (not great examples) you might put scroll work and or a perfectly rendered cityscape in the fore- or background. I think you're on to something interesting.

Interesting drawing but it looks a bit too crammed onto a shirt. Perhaps play around more with composition to make a stronger graphic.

I agree - not too sure what is happening here. Perhaps mix up the contrast with different colours?

i like the freehand feel of your designs, but same as the above, you can put some contrast to give the artwork some depth. :)

Wow, I'm not sure how you dare call this design/art - awful. I'll keep an eye out for more of your work...
