The placement is a bit awkward. Maybe move it down a bit so it bleeds off the bottom, that way you're not crowding the globs at the top. The scribbly marks at the bottom are a bit out of place too. Maybe try making it look more like globs of floating stuff instead of a mound of chewed gum.
Also, this would really pop on a blue shirt. Either navy or turquoise.
I love the idea and placement, perhpas some different color variations? Orange is nice, but I think that a lot of people don't wear orange. I''d wear this one though. just a suggestion.
wow this has progressed nicely. i agree on the purple shirt not being the best color. Just a heads up, i read somewhere that threadless only does single color belt print.
i like it. depending on the shade of red of the shirt and ink, you may need more contrast or some kind of light outline. and i would suggest pulling it down to the bottom (see the dotted line?).
can't tell you anything that i see but make sure you read thru the subbmision packet again... it might be a small detail you are missing...
on a different note have you tried to maybe size the design differetly? work of of the shape of a lava lamp and place it to the side (right maybe) of the tee to make it look more like a lava lamp...
There are some tee textures floating around, you should present this design on them instead of a blank tee. Also, I think this would benefit from a little softness, like anti-aliasing. Just a touch, to get rid of some of the sharpness.
And it's funny, but I actually like the analogous colour scheme better than the complimentary one.
I think it is a bit too large as well; there should be some more space around the design. Shirt colour choice is great though, nice use of complements. Comment on mine?
