Hi Fracco.
I won't continue with concept #8 as I have enough variations of that concept already.
Concept #11 is interesting.
Can you bring a gloss effect to the logo? - I use a lot of power point files, and they look great in that setting.
I like the balanced look of the text.
Any variations of the yellow block or ideas to give the text more punch would be great.
Cheers. Stan Greene.
