Coffee Thermos : need some advice!

Hey guys! I need your advice.
Knowing that Thermos will also print design that won't be printed on t-shirt made me tought about a design I already submitted. It's "Coffee Splash" I did it as a Summer Sequel to my printed design "Coffee Cloud".

I put it on a Thermos for fun, and it look good. I was wondering, do you think I sould resub it for the contest? Should I put it on a t-shirt also again or do you think it need some more work?

Thanks!
