Sounds like you've got the right idea. Nothing wrong with creating an aesthetically pleasing habitat as long as it's suitable for the snake! I've seen a lot of nice set-ups in PVC cages so definitely check that out. You can also go the DIY route with a wooden vivarium if you're handy. Just avoid that screen! I'd also recommend doing some searches on environmental enrichment for snakes and reptiles, it's a hot topic lately so you should be able to find a lot of good species-specific ideas.
