I'm not a prospective buyer but it's a lovely looking bike you have there.
+1 but only as it's far too small. It's a really lovely looking bike. IIRC you haven't had it very long have you?
I am with lilolee though. The devil is in the detail when advertising something like this. Loads of photos, close ups of the lug work, fine details, mechs etc, and really describe it as if your describing your first love
FWIW. If I was photographing this bike I'd level the bars and adjust the levers accordingly, (this would also allow you to re-tape the bars and cover the lever clamps as well), put the chain on the big ring and the small sprocket, level the crank arms, put a valve cap on the rear tube and position the tyre logos symmetrically, and if possible get it outside in the daylight. Maybe a local park or something when the sun's shining
It may sound anal and unnecessary, but as I said, the devil is in the detail.
Good luck with it
