umm, youre pretty good... from what i've seen.. *cough*
1) the face is kinda.. um, the lips bother mehhh... the clothes are really pretty, but the wrinkles look kinda.. unnatural. well, it doenst REALLY matter, but it would be good if the pearls had the little reflected light instead of making it dark on the edge.. like this:

2) urrr, you could use some practice on the hair.. and the clothing folds(again) XDD the leaves/feet kinda looks unnatural.. (only some) and the hands need practice..(i suck at hands too)
3) i like this one so far--i love the perspective!!(i suck at drawing those kinda perspective!! i tried.. trust meh.. -__-) its really the same thing i said before--hands/clothes/hair... but i really like the pattern on her shirt!
4) oooh, their clothes are really cute!! i say the body proportions are little weird.. kinda off.. and the legs are too straight--not natural..
5) the hair seemss... little weird.. and the face features are.. kinda distorted??
6) DD= they seem stiff.. same thing i said.. there face.. hand.. body.. but youre better at backgrounds then meh. DD= i SUCK at backgrounds...
7) FACE looks weird..! and the foot is too small.. i like the upper part, but not the lower part..
foo, that took a long time.. XDD do you use markers??
