Sorry to say but bryce isn't a modeling program and render times in bryce are a joke. I used bryce for a long time so I'm not bashing bryce. I went from bryce to max. Sure the change in interface and all the new fetures can be intimidating but hang in there and you'll be glad you did.just start with one thing, say splines, and just explore all the options you can use on them. You'll soon get the hang of them. Then try something else and so on. I'm sure there are tons of tuts for lightwave out there.
