It seems extraordinarily flat to me. I would light almost directly from the side and a bit above, just enough forward to get light into both eyes. I'd also only use one front-light, or if you must use two, crank the fill waaaaaaaaaaaay down to almost nothing.
With a bigger guy like in the first photo, I wouldn't have him facing perfectly to the side--it emphasizes his thickness, and his fiancee seems to disappear into him. You did a good job of getting him looking down a little bit to avoid glass-glare (cripes is it a pain in the arse to re-build an eye in photoshop!), but his frames almost cut through his eye--a very fine line to tread.
In the 2nd photo, she's a very cute subject, but here she's slouched down and facing directly at the camera...makes it look like a mug-shot.
