Thank you so much for posting brief on design crowd.
i will submit my designs asap,

here are some quick tips for you :)

1. Please Google "overused & Generic Logos" and avoid them in your contest to stay away from future copyright issues.

2. Dont make any decisions on the basis of "free Photoshop Mockups"
Logos may look really nice on Mockup, but it doesn't mean they will work properly when you actually use them in reality. for example. Business card, letterhead, mug, 3d wall, golden foil, embossed etc.

please support original, creative and hard-working designers. Good Luck

I agree many Contest creators gets fooled by this.
