Black Chopper

This is my first submission to Deviantart and my first real completed work. Some of the parts of the bike are inspired from an actual bike made by Billy Lane, but the rest is from my own imagination. The rear wheel is a hubless wheel design, meaning it is not like a normal wheel with an axil and spokes (makes more since when viewed from the other side, which will be comming soon). Please give me some feedback on what yall think and how I can improve it. THANKS
