There should be shadows on the head from the headdress, and the edges of her skin are ragged. Yellow cast in foreground & background kills depth.

so pretty and sweet!!!

The edges of the mushrooms are also very ragged looking and poorly cut out in the stem area. The line along the top of the breast is particularly choppy looking and rough edged. All of the elements show a dark outline of 1-2 pixels, except for the top front of the woman's headdress, which shows a very disconcerting white edge on the face side, and a strange dark "blob" on the back. This visible extraction outline can be corrected if you contract your selection by 1 pixel, invert your selection, and then delete.

Congrats!!
