Thanks! Considering this whole process has basically been 3D improv ('Right, I have a box. Now what happens if I move this down here? Huh, looks kind of like a spaceship. Let's develop on that.'), a comparison to existing work is quite a compliment.
Apart from the initial, 'OMG I'M MAKING A THING!' excitement, I've felt the need to keep posting progress updates to demonstrate what you can do from a total newbies perspective. With Teague's tutorials, a little Googling and some thinking - you can make some pretty cool stuff.
