LeMans: LR is a good photo only program. It isn't PS, for 'moving heads', layering, etc. It took me awhile to get OK at it, and I find that for better/realistic pics that 'less is more' in terms of adjustment(s).

Resist the urge to over sharpen and lay off the saturation slider, imo.
I still have LR3 and haven't paid for the up to LR4...
