This is really pretty cool! If you don't mind a little more advice 
, you can withdraw/delete your entry for 24 hours after you submit it; there should be a little red X over it that you can click on. This would allow you to resubmit the design to another site immediately (otherwise, you'd have to wait 60 days to submit it elsewhere based on woot's rules). However, you can also resubmit it to woot if you can juggle the design to fit woot's printing rules. There are templates available for download that show the printable area (for woot) on a shirt (the links are under "Design Guidelines" towards the top of the page): your entire design needs to fit within that 16" x 20" area (i.e., the only place ink can go is within that area). Woot can't print the black extending all the way to the bottom of the shirt; I think your design is also too close to the sides. If you have trouble with the template, try posting in the Pre-Derby discussion thread; the artists are generally good at helping newbies with technical issues.
If you want to resubmit, I'd suggest that you definitely want to withdraw your first submission. This isn't a requirement, but the Rejectionator won't be around until Monday, so you'll "steal" votes from yourself as long as both designs are active. You want all the votes to go to the one that won't be rejected.
FWIW, if you want to resubmit, I think the effect might be more effective when printed if it's on a black shirt rather than a white one. That would allow the black "effect" to extend to the bottom and sides of the shirt, and you could use white ink to extend the white effect almost to the sleeves/collar. Based on studying visual perception from a cognitive neuropsychology perspective, the eye will perceive the black ink ending into a white shirt, if the basic shirt "blank" is white, as very jarring. If the design is on a black blank, the white ink at the top of the shirt will not be jarring to the eye/part of the brain that processes optical illusions.
neuropsych trivia: this has to do with how the brain processes negative and positive space when evaluating a "multistable percept." Multistable perception is one of the main visual phenomena behind much of Escher's work.
