Could someone check this Pcb Layout? (ESP Miniature Audio Oscillator)

Could someone Check if there is any errors in this layout (this is the most complex & biggest layout so far I have done).

Here is the Schemo. http://sound.westhost.com/p86-f2.gif

BTW is this too messy to trace? I tried to make it as logical as possible, but the circuit was kind of challenge to me. Is there already a layout floating around for this if this happens to be so full of errors that it's hopeless for me to fix them?

I don't have time to trace it for you but it looks pretty logical and laid out well at a glance.
Get a colored marker and a copy of the schematic and the layout.
Go over each by marking section by section in the colored pen. This way you can trace it out without missing anything.

Nice work.

Thanks for the tip John. That was new to me . I'll have to start to trace this right away.

Ok. I found some errors with your method. The R1 C1 junction wasn't connected to the IC pin 8, now it is made with insulated wire. I used same method to connect pin12 to S1, 2 and I added a missing junction between R15 and R14.
   And thanks again John, that your tracing method was really effective.
Here is the corrected layout, still unverified but I think it just might work.
