lovely... few things
right a few things to point out... the skin is lovely... the tones are fab and i think you shouldnt change anything... apart from...
posibly tone down the earing as they seem rather bright (fake) , make that thing around her neck fit better... possibly some shading under it so it doesnt look like it was put ontop of it... along with some shadows under her head *on the neck* put in her missing arm, and on her arm make the pink/white tone go alot darker towards her side as its to bright *like you did further down her arm* but do it all the way up to where you started doing it again :P... its like you forgot to do it... i like the shine effect but the whole body could use with the lines smoothing up alot, like the lines with gold in on her brest as well as other places... the hair is flawlessly done and i love the face... fantastic for your 5th try!!!...
