In addition to the other excellent suggestions I'm concerned about how close you have placed traces to the top edge of the board. Perhaps they are 50 mils off, I can't really tell.

How are you mounting this board? I see what appear to be two holes to each side of a big connector. Two isn't enough, and those appear to be related to the connector.

As has already been suggested, add the ISP header. You have to have the ISP to put the chip in JTAG mode. You have to have the ISP to recover from certain goofs you can do  in JTAG mode.
