A bit of constructive criticism, since you asked...
Personally, I'm a big fan of keeping it simple, especially when it comes to business cards. Clients rarely, if ever, look at a business card to see what services you offer. They use the card to get your name and contact info, period.
I also have to admit that I have never seen the phrase "All Orders Require a 50% Deposit" on a business card. In my opinion, it comes off as tacky. It also doesn't help that it is in all capitals, which is the writing equivalent of yelling.
So, I would personally rethink and redo the back of your card.
As for the front, I find the colour scheme doesn't flow, and the background "rainbow and stars" combo looks out of place and busy. The text is just all sorts of wrong.
Bottom line, your card looks alot like what a client would bring in as their "I made this in MS Paint" starting point. It does not scream Graphic Design Professional to me at all, which, as a Graphic Design Print Shop, it should.
I'd look at this as a first draft. I have no doubt that many of the fine members here will be able to provide ample feedback and suggestions to help you move from this version to something far superior. So, give it a few days, take in the responses, absorb them, and give it another run.
I look forward to seeing the next attempt!
