Well.....
This really isn't that good. And to be quite honest, everything you have is not scout worthy.
With this piece, you really need to work on anatomy.Your character here has some badly exaggerated proportions.
The logo it's self lacks many elements associated with graphics and logos. The type you have is crude and suffering from lack of structure and knowledge of typography.
The line quality is pretty bad and very thin in some areas, again going back to the elements of graphic design.
You really need to work on your character and graphic design. Don't be afraid to use rulers and shape templates, they come in handy and save you some tedious work. Get some better line art and try this again.
