Ok, here are my comments. Please note, they may be wrong. 1. You have some extra stuff I don't understand on the board. There is a little square of holes with an extra hole on top (total 5) between R5 and INPUT. There is also an extra hole above S1 2. The trace between pin 8 and pin 9 might prove problematic. This seems to be a problem all over your board. Personally, I would try to route in orthagonal lines, plus 45 degree lines. Asthetically I find differing angles to be less visually pleasing. That said, The trace between 8 and 9 might cause you problems as it isn't straight, and you may find it too close at one side. 3. You may want to fatten up your traces a bit. Beefier traces will be easier to etch if you're making the board at home. Your board doesn't seem that complex, so you should have the room for them. 4. You may want to put an in circuit programming header on the board. Again, you have spare room, and ICSP is much faster than having to pop the chip out each time you wish to reprogram. 5. The +V trace that runs by the cathode of the LED looks awfully close from my view. Couldn't hurt to move it away slightly. That's about it for me, I'm sure others will comment as well.
