Speaking just to the Guzzi... Pretty bike but for me I'd like to see a more complete continuation of the rear sub frame along the bottom of the tail piece contour. The current look is a bit too much of the cut-it-off-street-fighter look for me.
Also, more responsible tail lighting. I'm of a stage in life where fashion no longer trumps common sense.
Too, demonstrate a truly complete concept by displaying one's notion for hanging a license plate other than a couple zip ties under the seat or sideways over the swing arm. license plate mounting finality has long been my litmus test for a "designer" having a fully formed concept.
Still, better work than I've done lately. Tank work, exhaust and overall proportions are excellent though the rear suspension geometry - sweet looking as it is - gives me pause.
