Are you using 3dsmax with skylight? Maya with physical sky/sun? or is that Vray? If its vray i dont know, never used it, but it looks as though whatever your using it doesnt have samples set high enough. Also, the blurriness is a filter issue, but again, I dont know what app ur using...
the red places render strange...propably wire problems there
the blue place...i think that u got to dense mesh there that will be hard to control
the green...the chain...looks plastic and unnatural a bit, try to find chain tutorial on the net, i remember i saw one somewhere...and try to learn rope simulation...that will give the chain more realistic look...or u can just remodell it. Keep it up man
Catlin knows what he is talking about i am doing that.
The wire is good and i know it the problem is in rendering and that skylight and everything
For the Chain i know the rope simulation i did it that way and i don't care if it doesn't seem like real xD
it is just for fun
Here are some updates :/ the back is not 1:1 i dunno how to make backlights but it will look just find
next part the rims
