Ok, so you now have the base of your company: the name. (Stick with Butterstick, as nearly everyone stated above.) The next step is to fine-tune everything else. First, the "mission statement", as Sneaky turtle said above, looks like you wrote something , and then used a thesaurus to change every other word and make it sound smart. In reality, it took away from the small business feel and made your company sound unprofessional. Instead, it should say something more personal, something more memorable. Maybe something about the start of your company, what you do, or who the founders are. it should be simple and something that sticks with people.
Once again, as many others stated, get rid of the B crown.
Now, for the designs. First off, I notice that you have only three designs. This is good, as it starts off simple, and comes off as being easy to handle. However, personally, the idea of having a so-called "Little Wayne" on a t-shirt that comes from a small company is sub-par, and once again, unprofessional. You have a small company and shouldn't create designs with pop stars or recogizable icons on them, leave that to the more general companies. Your designs should have more of a connection to your brand, and above all, should be ORIGINAL. There are many different options with the name you have, and many more designs you could come up with. You should make them yourself, and make them be something that, in the future, people will associate with the Butterstick brand. Come up with an original logo, and put that on a shirt.
Overall, start off simple, with original designs, and a product people will buy and associate with the Butterstick brand. Once it is well established, then expand, come up with more products, and good luck to you.
/rant, just some things that I believe could improve your business model.
