Thanks Jake, it took a lot of work to make it look translucent. It's not actually translucent though, if you put it on any color background, it'll stay the same color. >.<
Also, I think what Crimson is trying to say is that in perspective, things get smaller as they get farther away. In your case, the back of the tower looks somewhat bigger than the front, although the front is closer.
By the way, I like the texture you put on the front, it looks awesome.
