Welcome to Gaia! ::

The first one's breasts hang wrong. It's not very obvious until you look at the leaf thing covering where her n****e should be, as it's much too high and too far out.

That and the fact that you have a tendency to space people's eyes really far apart. Eyes should be about one eye's width apart, yours tend to be 1.5-5 eyes' widths apart.

Otherwise, though, I must say I do like your style, especially the way you render muscle.

Your blending is very good, but I would reccomend taking some of your pictures into grayscale and checking the contrast. Low contrast is fine, but for dramatic images like the top one, higher contrast means higher drama. So darks darker and lights lighter. You can do this easily in photoshop by putting a color layer over your image, filling it with white, then making a new overlay layer over the top and painting black to create shadows/white to create highlights. Sometimes this means sacrificing detail, but the human eye is great at filling in detail with only hints to work off of. Giving the viewer every detail clearly can sometimes detract from the interest of the piece.

Also you're using a lot of colors at similar saturation. Play with pushing saturation far down for less important elements (or things that are further away) and use high saturation for prominent elements or foreground objects. Remember you've got the full range of values to work, but once you're at 100% or 0% there's no way to push it further. So think around 50% and go from there.
