This is exactly the style of artwork that we were looking for. I would like to make a few changes if I may...
1. The character should have a face. You can leave the glasses off- they do look cool though.
2. We like how he his punching the Brand Brawler. Can you work on creating/enhancing the Brand Brawler part of it there will be times when we can not have the character with it and would like the words to be strong on their own, so anything you can do to further develop this would be great!! We used font cc zoinks, but anything you are feeling creatively will be appreciated! We like the yellow "pow" kind of sun burst so if you will continue with that and just further develop this I think we are almost there!!
We do have an appreciate for comic book style so if you feel the need to take it there feel free.
Will not be so professional from my side to take inspiration of another design, but here is a proposal of my own, hope I got the idea of what you want the company name looks like.
Work in projects outside Logotournament? yes of course, when the contest be completed or you decide to complete I can give you my personal mail so we can work together any project, character positions, new characters, etc. You want to work with me. :)
