Haha, I recognized the palette right away. That was a fun challenge. Great job, too bad you weren't here for ours(though there were a ton of entries).

super sweet! Love the design!

I really like this :]

I know you said using a pre-made pallete, but i'd suggest you maybe go back and change the colours. (you can always submit a new piece just stating that you revisisted it and added more contrast)
Looks good :D

Lol, we have had this same challenge here. I see 7even (un7 on your board) has launched them on both places ;)
