Perhaps a bit more specific comments would be more helpful? Like, what problems do you see, and how would you fix them?

I would suggest building two boards one lm3886 on both . It will be easier for you to get a good layout it is good to keep + _ power traces together. keep fb loop very very short even solder fb resistor direct to the ic. keep inputs and outputs as far away from each other as possible. also keep input away from power traces. pin 7 should go to power ground also the ground side of the 0.1uf decoupling capacitors direct to power ground.
I am a newbie but i hope this imformation is of use to you .
Good luck Ian
