I like it, you've made something that fits with the premise of the story pretty nicely, so you get a thumbs-up for that. Approved.

Make sure you add an appearance. The character itself is fine, but the High Specialization feels a lot like a "multiple in one" sort of deal. Street Performer is a combination of Dancing, Instrumentals, Acting, and Misdirection/Subtlety/Thievery. Out of those, stealing would need to be its own category, as would playing instruments, but you would be able to combined Acting and Dancing pretty feasibly, so just think on what you want to do with that. 
The Body one is fine, since it's just a general physique thing, but it's helpful to remember that it won't increase his reaction time or anything like that.
But yeah, so my recommendation is to split up the Street Performer into two Specializations, maybe the thievery stuff on one and the dancing/acting on another. Since you have a Low Specialization slot open, that shouldn't be too hard to pull off. Just do that and add an appearance, and you'll be good to go.
