PWM H-Bridge circuit

How is this? I'm still not exactly sure how to size the fets. I got these form someone using a similar motor (around 10A). But they are rated for 8 and 6.8A. My motor isn't marked but I found documentation that leads me to believe that it is 2.8A no load, < or = 9A, and 28A stall. The app will not require heavy loading and will probably never run at full load or speed. Also have I used the driver properly?
