Thanks all, I am pursuing each of these suggestions as I write this, and I'm sure I'll achieve some noticeable improvements. When I have something worthwhile I'll post it as an example of the progress made :) In the past i have been loath to messwith lights, as they seemed a bit complex. But with these mentioned ones, am I correct in assuming that I just load them in once and then leave them alone? No further manipulation required? I will be reading the tutorial but I just thought I'd get a quick idea here. Thanks!
