Love the design and atmosphere you chose for this in the end, I remember that I was going to comment on your design choices back when you posted, but got distracted by life and forgot.
If you want to do even more work on it, the grill and the nose cone on the front of the speeder are not in line with a flat frontal vanishing point, but its pretty minor and given the detail and lighting it dosn't stick out very much.
Great work.
