You will need a much wider trace for power ground and for power in. The traces you have are much smaller than they need to be.
I'd put a diode in front of the 7805. It can help a bit in odd shutdown situations.
You might think about automotive fuses in place of the PTC parts from Bourns. The cost / board space is no worse and they work a lot better. If you ever decide to go above 12V they will still work ok. The Bourns parts are only rated for 16V. They also have a maximum current rating that you may or may not comply with on this or that power supply. Yes they are used on a lot of these boards, they also fail on a them as well.
