C10 looks like its incorrectly wired in the schematic.

I think your high power traces (it is a high-power motor driver, right?) are MUCH too narrow.
Agree with charlie that there is something wrong with the xtal/c10 wiring. Shouldn't both sides of the crystal connect to the micro? Do you really want trimmer caps here?
Bypass caps should be located close to the power pins of chips.
GND of mega8 doesn't seem to be connected. The 8pin chips also have a disturbing number of unconnected pins, but I didn't look up what they actually are...
It looks vaguely like the board would route better if the mega8 were rotated 180 degrees.
