Edit : After taking the pic, I rotated the resistors R5 and R9 to make connections easier.

Any more suggestions?
Lots, really lots.
More of the above, much more.
You are gaining the vision required but keep looking and looking and after an autoroute of two you will see more. Pick a net or two and focus on getting them the best you can the rinse and repeat with other nets.
At a glance a few simple pointers.
Flip and lower D6 so to run the GND trace around the top to J3.
Flip TH1 and R8 then you have just one trace to sort out the routing for and lift it a little and run the trace along the edge of the board.
Move Q2 to between Q4 and U1.
Consider rearranging Q1-4 and associated components to allow for easier/better routing.
Don't bunch SMD passives too close to bigger components. (later you'll thank me.

)
Tidy up labeling even though after routing you may need to do it again. Use same font size for all.
That's an hour of two's work to sort out and enough for now so to not piss you off too much.
