Very nice!
I only think boards in US are a little expensive, in my town they would cost 
about 1/4 for what you paid (the one from Advanced, with soldermasks and 
silk) but salaries in US are far more than 4x the salaries in Brazil, so, 
there is no problem at all :D
I am curious, opening your .pcb here shows that you used layer 1 and 4 for a 
double sided board. I think you changed the colors of the layers, because 
here layer 1 are brown and layer 4 are read, with that kind of colors is not 
easy to draw the board :D 
I am curious too to know why you mixed thru hole with smt components. 
I have olny one suggestion, allways use oblong pads for TO220, it makes the 
design and the bulding much more easy, I attached my TO220 footprint if 
someone wiches to take a look. 
But what I really liked is the graphical display, I didnt work with one like 
this until now, how did they cost?

Anyway, congratulations, if you are as happy as I become when I make a circuit 
works, you will have a happy day topday :D
