For general sport flying it's fine as shown but if you plan on stunting it more aggresively then the elevator hingeline should move forward so the overall stabilizer is about 1/2 movable and 1/2 fixed. And I suspect that the nose is going to be a little bit too long to get the balance point at a position where you can do snappy stunts. You're looking for a CG that is back around the 25% point to ensure a responsive stunter.
