that IS a hot bike. i agree that a brooks and matching bar tape will make it sexier. i know many others will also agree with clips/straps... it would make it look more original, but i don't like them myself, i really enjoy clipless, but that's just me.
is that the original seatpost? it looks kinda like a cheapo kalloy i have. anyway, if it's a cheap one, get a nice one. other than that i wouldn't change a thing!
p.s. that fork is the hottest part of that bike, imho
