Have you tried simulating it?

The great thing about getting results in engineering is being able to rationalize your answer. In this case, run through the logic and verify it does what a 3-bit, positive edge-triggered counter does.

With two input signals you have four possible control states. While what it should do in two (and arguably three) of them is fairly obvious, what it should do in the fourth is not. So before anyone, yourself included, can tell if the design is correct you have to first clearly specify what the design is supposed to do.

Is it right or wring
Walk through it and figure it out. It should only take a few minutes to build up the transition tables to verify whether it works correctly or not. If you run into problems, post what you've done so far and we can help you figure out how to move forward.
