I like your website and your designs....pretty cool and it appears you have put a lot of work into this. I would probably wear some of it. What loses me is the "Brootal Doodle" title that is written on the shirt. I like the name of your company....but in my opinion, it is the type of name that should be on your tag or worn by you and used for company business...and not featured on the shirt. The name seems cute and clever to me, but not something that your target crowd would likely be drawn to...on a tag sure, but not on their chest, etc.
I think if you focused more on the art...and let the brand name take a back seat on your product tags...you would sell more shirts...especially to a company that might want to carry them. Companies like Hot Topic carry a lot of image shirts...but most of their shirts (if not all of them) do not feature the t-shirt company name on them. Even the most established ones do not tend to feature their company name on the shirts...they just focus on the licensed material or their own custom artwork. Just my .02 Keep at it...you have a good thing going and it can succeed if you just keep after it.
