Often what I do to create a background is to create a dome, shell it, cut it in half (so it looks kind of like the sydney opera house), then place it around the scene. It's kinda cheating, but it'll surround your model with a seamless background to which you can add a nice sky-like color or even a sky material with clouds and such. Check out the attached pics to get an idea.
Hope this helps! Keep up the good work!
