You guys have a very strong base for a great banner. I agree with a minimalist, but visually appealing design approach which I why I like the black company one so much. It is stylish, yet not over-designed. In fact, a little extra flair might be all that would really benefit this banner.
I wanted to revamp your banner in a more neo-modern sort of way. Keeping your strong base, and just sprinkling some detail here and there. Overall, I am very satisfied with the results, and hope you will be too.
