#8,10 and 5: lack creativity and brand values of fun, bright, dynamic. also don't restrict yourself to color brand colors, pls experiment #1 and 2: will become increasingly tough when scaled down to be legible also issues of uniformity and balance
We are looking forward to some real cool concepts coming from your end! Try a colorful rendition of #9 and see if something interesting can come by thinking completely out of the box. Waiting for some awesome designs coming in soon. Cheers!
