now that is one badazz bike!

The headlight is too bright, and the star lens flare effect compounds the problem. The light would not be so bright unless it was looked at directly head on, not from an angle like the rendering. You also have a too-bright reflection on the side behind the light, which simply would not exist, unless the light is somehow leaking through the metal.

The rear wheel is quite interesting, although I bet it doesn't get much traction

There is actually 4 light source in the scene.

The head light actually contributed very little to the scene, and it is pointed in such a way that you can see the bulb is visible from the camera.that is why the flare and Glow show up.

The reflection is from the main Light that is to the right of the camera which contributed most of the light which made the scene visible. You can see the shadow cast by the handle bar on the tank.

There is also a Red fringe light to the left and the Blue shadow light from behind the bike..

I don't think metal wheel will get much traction. Was going to put some spikes on them wheels. Note the steering on this bike is on the rear wheel.

gotta love slicks!

wow and wow again...fantastic creation author...well done

Aside from the model's attire being too contemporary for a Steampunk ride, the bike has some great elements to it. The wheels and top cover, not so much, tho, the outsides are way too contemporary, but the inside parts are cool, as is the hydraulic system, reminds me of a steam train. Would have loved to see an exhaust pipe with steam, too, but overall a pretty cool ride for the moonlit night.
