What you've done with them isn't bad, overall. They look a little overprocessed, to be sure, but that's easily fixed.
I don't know if you're using canned actions or if you're doing this yourself, but the desaturated high-contrast-midtones, desaturated, is a popular fashion look these days. You're going warm toned where fashion usually goes cold toned with this. The main thing is that you're doing a highly recognizable stylistic thing here, which is likely to make the customer think of fashion photos -- this is good marketing. It's not a look I am in love with myself, but that is a matter of taste.
I would back off the processing a touch, apply various effects less strongly, and call it good. The backgrounds and so forth are pretty good and pretty well handled. Others have raised some points on posing that are worth making note of, but generally I think the "straighten this" and "move her hand there" are fairly minor quibbles. Yes, the watermark is kind of big, but people on TPF just love to complain about watermarks, so you can pretty much ignore that part.
