Love the simple character design here. I think that zebra has potential for his own little animated short. He's just neat. He looks a little psycho in this particular instance- it's almost creepy how enthusiastic and happy he is dancing around that kitty but it's cute. Unless it's a requirement for your flash project I'd say get rid of the start button... it should automatically play (that's just how ads usually work). The sign could still be there but have a different message like "visit soon". I like this over all very cute!
Uh hirurux, sorry my friend, it's been a very hot day, I mistook talinuva's comment for yours...My apologies to you! Anyway , I think it's great way to spread a positive message. And I still think the characters are adorable and charming!
