Denner, I took a look at the work posted here along with your Behance site. Overall, I think your work shows some potential, but you could use time, education, and tutelage to settle down a bit and improve.
As @Smurf2 pointed out, you have a typo in the logo. Oops.
Regarding the design of the logo, my personal feeling is that showing keylines or guidelines is a tired option and a bit of a cliche. In your case, they seem to be somewhat randomly placed. Plus, they aren’t needed if you have a strong mark. Do a study on the mark without the lines.
I find the Sigana font to be a little much when used as a display font. It’s okay for the logo, but for longer words, it becomes a bit tough to read. Consider use the Neo Sans for all of the type other than the logo word mark.
As @Just-B said, I’m not sure about the 3-D rendered guy. It’s a nice enough rendering and it could become a branding element, but, right now, it seems like a space filler without a good reason to be there.
I’m lukewarm on the Photoshop mockups – and this is a general statement, not pertaining just to this project. On the one hand, they are cool looking. On the other hand, they have the ability to make a design look better than it really is. I’d rather see the logo applied to a business card, website, collateral, etc.
Bottom line, you have a start here, but it needs some refinement.
