ok .. i actually had to google the real meaning of tacky ..
"not having or exhibiting good taste: such as. a : marked by cheap showiness : gaudy a tacky publicity stunt a tacky outfit. b : marked by lack of style : dowdy."
anyway .. i feel you are satisfying this challenge absolutely .. !! ..
if you had a smile on your face it would make this even better .. just that it would appear that you have totally embraced your tackyness .. lol .. :)
Yep, pretty tacky :) Concept is excellent, execution needs a little more work (but equally, the over bright and slightly mismatched lighting do feel appropriate for the theme...)
