Take for instance your bay window in the latest version. Looks nice, but you really need to slope the top of the window or put some sort of awning or roof or something there to handle rain and snow. You don't have to worry nearly as much about keeping water out of the structure if you don't provide horizontal surfaces for it to pool on. What's worse, lets say the installer actually makes a small mistake and the top slopes toward the building a little bit. Now you have a funnel running water into your living room!
The sun room or whatever you want to call the glassed in area looks great, but you'll need to check local codes about using commercial curtainwall in houses. I don't do much residential stuff aside from the occasional apartment/condo complex so I don't know if there an issue there or not. At any rate, curtainwall products handle water by providing places for it to run to, collecting it and channeling it back towards the outdoors. For that to be successful, you need concrete at the bottom for it to sit on in order to provide a water proof seal. It also flexes quite a bit with wind and building movement so you need good structure next to and above it. Some products anchor into the vertical members at each side, some only at the top and bottom. I've never seen it anchored at the bottom in anything external but concrete or steel, and I don't believe any wood structure there would be acceptable for strength or the water issue.
You're off to a good start, and now would be the time to grasp some good design techniques before you develop any bad habits that will be hard to break. On the other hand, if you are looking to do purely artistic stuff with no intention of ever seeing any of it built, that's fine too. A good artist can make a lot of money if the right person sees his art. There's no reason you couldn't do both if you wish, as long as you remember what I said earlier...it don't matter how pretty it is if you can't build it.
