You are the only one that utilized imagery showing a person working. I like that. The "M" looks a little too University of Michigan for me, but I would like to see you incorporate more abstract imagery if possible. The slogan is not necessary or the name of the company as it will be present in other areas of the site branding. Please continue with the idea represented by the man though as that is unique to you.
Your design got a hug boost in feedback from friends and family. They like the incorporation of the time element and working. I do too. I'd like to see you continue with this them and incorporate my other comments(i.e. less letters more imagery)
Bam. You nailed it. Now I would you to make the background white or light colored. Dark backgrounds are hard to incorporate. Also if possible do you think you can make the halo fiery ?
