Well, I'd like to say this is actually pretty bad. The shelves are all identical, it's all blue, there's no roof or doors, and I probably could have done this in about 15 minutes.
A word of advice: Before posting anything like this, please ask yourself: Is this good enough? Exactly how good is it compared to other builds? Looking at this build, you may want to improve on your skills.
If you don't want to be flamed, don't post things like this unless you know it's really good. Just take a look at a bunch of the other builds already here.
I'm not saying you suck or any crap like that, you just need to post something much better next time you plan on doing so.
