The lead spacing on some of those resistors is just too small per the
resistor manufacturer's specifications. For a prototype it is probably
"ok", but not proving enough of a "shoulder" on the leads can result
in
cracks in the metal film inside the resistor itself. You might not even
notice at first because it may still work, but over time with a little
heat and humidity... It is just easier to stick with the proper lead
spacing and be done with it, even if the resulting board ends up being a
few cm larger.
As for the angled jumpers, that likely just means the board routing needed
some additional hand tuning. It looks much nicer if the /traces/ are
angled so the jumpers can parallel the orientation of the resistors and
other passives. For that fact, it would be even better if all of the
headers and connectors were located towards the outside edges of the
board. Boards with connectors clustered around the inside at random just
look less professional.
I dunno...it
doesn't look all that bad, and through-hole makes assembly
easier for most people. ;P
That is the point. Not only you can build your board, but also make it.
The first prototypes (single side with top silk) were done at my house.

The main thing I would have done differently with
the board
design/routing would be to avoid turning resistors and jumper wires at
odd angles and widen the lead spacing for the resistors where it is
-really- small. Some
Why? It shaved some jumpers! :oD
