Hi UVDan. Nice first attempt. I was the same, once I'd used IBL I did'nt want to go back to Bryce's standard lighting mode.

It is worth it when you get the hang of it, the results are much better.

Just stick to it, you will be pleased with the results.

Here's my Gallery images all done in Bryce 7 Pro with IBL and some using HDRI's as backdrops.
