Learning Sketchup

I've known about sketchup for awhile, but only yesterday did I decide to actually sit down to learn the program. Since Richard and I have been reading the Chrestomanci series together, as practice I kind of wanted to make my own version of Chrestomanci Castle. I was interested in the idea of a castle with multiple towers of different sizes, and parts that were old and new having an odd sort of mixed-era architecture.

That was the idea, anyway. This is what I came up with. It doesn't quite fit with how I imagine Chrestomanci Castle, but I had a lot of fun with it while learning the program and now I kind of want to incorporate it into some kind of story now.

Next thing to learn I think is applying textures to the walls so they actually look like they're made of stone/brick. We'll see how it goes... wish me luck!
