Laying out an AVR Board V2
I still strongly suggest you move c3 and c4.



They should be on the inside as shown below, and keep those two traces as short as you can.



You might also want to double check the landing pattern on that crystal. The pads look a lot wider than the device itself.

ALSO

Unless you have a specific reason for the orientation, I would consider rotating that layout or moving JP_LCD to shorten all those traces.

Your decoupling caps should be as close to the power pins of the device they are associated with as you can make them. Having them half a board away is pointless.
