I designed a PCB. What''s wrong with it?

Well, this is certainly why I like the Basic Stamp. It is really an
opportunity to _stretch_ my skills! So, for the first time, I decided
to design a PCB layout. I used "pcb", an X-Windows (UNIX/Linux)
application to help draw the shapes.
It is here:

The board is 2"x3.5". It controls 6 RGB LEDs based on the I2C two-wire
protocol. It is based on the MAX6956 chip. Towards the top are jumpers
which are used to select the address of the chip (16 possibilities).
Towards the right of the MAX6956 is a connector which would support
power and interface with the BS2 board, as well as connect one LED
board to the next one in the series. (Each board would connect to the
next board in the series.)
Three major mounting screw holes are distributed through the board
(two towards the top, one towards the bottom). At the bottom of the
board are six 5mm RGB LEDs, which are capable of display one of 4913
colors (17*17*17).
But really, the main thing I was wanting was some critique of this PCB
layout. Is this realistic? Is this something I could give to an
experienced person to produce? Are the holes for the LEDs and the
wires too close to work with? Too many resistors too close together?
Any obvious mistakes?
