that's pretty cool, I like it a lot.. I guess you did it on purpose, but I wonder if it doesn't lack a little bit of depth.. (by using different value of lines, you could have create some further and closer parts (and still keeping that style) but this is really top notch and great idea!
OMG! It's awesome.. so many details.. i'm still looking at it, and i'll stay like this for a long time, trying to see every single detail of it. Great job.
