Very nice looking concept so far. There is a couple of perspective issues which in turn will cause other problems down the line. The first is that rear fender,right away it makes it a challenge just to fit correctly the rear wheel because if you fit it correctly it would look like what I'm showing you more or less that rear part of it would be very visible and would expand outwards. Then there is the front where the far side goes too far forward making it longer on the far side which shouldn't be since its further it should look smaller and more less how it looks now. I hope you don't mind me showing you this pic with the rear wheel positioned more less correctly so that you can see what i mean about that rear fender and the front i warped it to more less how it should be. I hope this helps. Excuse my English and good luck with the final chop.
