Anyone like to inspect my schematic/board?

This is the first time i have made a eagle file or designed a board for that matter. It is a arduino board to hopefully be used in a upcoming AGV. Just want someone to check the schematic (which is bloody horrible looking in eagle), and general design. I was trying to keep it under 5cm x 5cm. I might have missed something or maybe just designed this board wrong.

... but here are a few things:

- the schematic is so ... eh how to say ... obfuscated that it is very hard to read - that's OK if you understand it, but it is very hard for someone else to read, try making it larger and remember that you do not have to connect all power lines together you can just add GND and 5V symbols where they are needed.

- try adding a ground plane for the underside it will make it a lot simpler to trace the rest of it - also it would help with noise.

- there is something strange with the pins on the JP7 pins, and with all 3 pin connectors, the middle ones are strangely misaligned in regard to the side ones , you need to fix that or you will get in trouble getting the male headers in there

- is the reset button really required? I mean you can get some more space by leaving it out, cutting power to the thing reset's it anyway

- you did not add an ISP connector, I guess you will program this guy with an ftdi cable?

Please do take the above as advices, I know you put a lot of work in it :)

Swapped the weird headers with normal ones and took out the reset switch and added a gnd plane. The arduino looks correctly wired to me. Will hopefully get his made soon here http://www.seeedstudio.com/depot/fusion-pcb-2-layer-5cm5cm-max-10pcs-p-513.html?cPath=64_12

UPdated the board file.

Yeah i know the schematic is terrible, i havent been through all the eagle tutorials yet and do not know about symbols or anything but i was hoping someone would get something out of the board file. The "strangely aligned" pins are Sparkfuns way of keeping the pins in there when soldering, if it works for them then it should work for me. I totally agree on the reset switch. Yup FTDI. I will look into some ground planes.
