mate, for a first build, that aint bad...
i remember doing mine and i thouroughly enjoyed doing it...its a good buzz eh?
so, as far as adivce goes, heres mine....
drop the stem a little bit, 1 cm gap tops to your headset...pull your bars back so they are perfectly vertical, and thats the stance sorted...
then you have a good look at it, look at some other bikes in the museum, and you have another fiddle however you think...
thats what its all about..
oh, and clean your wheels..them grubby finger marks do it no justice whatsoever
welcome aboard mate
