Ghoang,

It looks good. Are you planning to make it yourself, or send it to a pcb company? If you're using toner transfer, keep in mind that the holes will not be plated. The pads and vias should be at least 500mil to make sure there's enough copper to solder to.

How do you plan to heatsink the fets? If you're using the Geckodrive method, you will need two holes for the clamping screws.
