maybe i'm jumping the gun a little, but you haven't said anything about my "shoot from the dark side" comment so, rather than be cryptic and annoying, i'll illuminate. (since it's a lighting thing.)
when i watch other guys shoot film and/or video, i can usually measure they're experience by watching where they're shooting from. guys who shoot under the key (or main light) are inexperienced. guys who go out of their way to shoot from the dark side, i.e, from the fill side or somewhere other than under or next to the key, show knowledge, experience, and get better motion picture images almost every time. this ain't an iron-clad rule, and there's plenty who might say this technique is more appropriate for motion picture shooting. and sure, there's plenty of times when you'll need or want to be on the key side or would prefer to be on the key side... but try your best not to shoot right under the key. (like you can't help but do when your shooting with a strobe on the hot shoe of your camera.)
i notice a lot of shooters, whether motion picture or still, seem to--almost always and automatically--gravitate to the key light for their position to shoot from: it often results in lackluster images. also, don't be afraid to pose your model away from the key at times.... sometimes you'll get some really great lighting when you do that. these are just some more things for you to try. you're really making improvement. if i could improve my skills as you've improved your's i'd be really humming!!!
