This are the logo concepts that I have received for my brand. Please let me know which one of them looks best and suits our brand. We manufacture a scratch protection film that protects the entire cell phone including its screen.
All the logos look great, but I think I'm most partial to the first logo -- it's simple and to the point without anything extra that the user has to think about to understand its meaning. The second and third logos also play on that shield motif, but the first logo is the cleanest.
I'd have to go with the third version. (The second logo looks sort of strange and the last one is well illustrated but far too busy.) The styling of the letters on this gives it an extra umph of strength, which is of coarse what you want conveyed. The colors are strong and classy as well... Reminds me of a yellow jacket which are some tough little critters. I'm not crazy about the actual font that you are using for the company name. It may be just me because I never did like this style of font but it doesn't even bother me much. I'd like to see a full presentation with other materials. Best of luck!
