What a cool idea. I agree with Endre. Something you would overlook but you made this turn out to be fantastic. Now I am going to look at my cars tail light to see whats in there. Nicely done and strong color.
Although I like the wash detail more in the second one, I think the detail of the red is more powerful overall. So I think you got the right one. Both are lovely
As always, well conceived and executed. Really catches the eye. BTW, I like your entry better than the alternate; IMO it is a "cleaner" image (And I'm not talking about the theme).
The contrast of the white foam in the second one makes a strong statement, but I prefer all the reflective qualities of the first better. Nice job. Good luck this week!
