design : it's ok , simple but nice color: Black and white is good, but try to give some creative color .
I like your idea for adding color to the tie. A Simple red or green tie would make the logo catch the eye and smack of professionalism. Not too sure about the mirror reflection under the second line of text. That's 'busy' for the corporate world. All in all I can see where you are coming from, it's good, professional, and still missing something. Good Luck with it
The second one i like more. The colors are nice but I would try to change black with Gray Metallic and the tie to be red.
I suggest that the top right one will do a better. The one in left will be not completely visible in a back ground like you have given. The bottom is seems to be a heading of a document. Try 2nd. Lood luck.
Looks great - Most posts seem to want more colour but I think it looks modern. The only slight issue is the man could maybe look more like a K? I wouldn't have realised it unless you'd mentioned it! I like it though and wouldn't hesitate to use it.
its good..... giving skin color to that LOGO... ll look good i think... its good LOGO symbolizes man power...
