Back off, I BITE!

Debating either I want this on a shirt, or poster, however, I want a saying on it, but I can't decide what.
But I'm also not sure if it looks good even WITHOUT a saying/quote.
Idk, but what do you guys think?
I had a lot of fun making this, and I was wondering if you guys know any good T-Shirt companies that have great printing quality, I would love to purchase one for myself and perhaps if you'd guys like, I'd make it available for you all too.
So, if you have any quote/saying idea's that may look good on here or go with the picture, I'd love to hear it!
Anyway, enjoy this little picture I whipped up! vuv
