Very impressive for a first flat !!
Magnificient hand-free paintings too ...
I have given a bit more lighting to the photograph ... a bit Under-exposed..
When you will have completed to surfaces, more highlights have to be given to the surfaces getting the light directly (top of head, right arm, the top of the wrists, .. ), and more shadwos on the opposite sides (along the right arm bottom left, the bottom of the wrists, neck and the right cheek, roundness of the bottom of the right 'jaw. Darkened shadows on the right arm Under the left fore-arm, and on the body too = wider than just a thin lining, willgive more 3-D effect.
Also your hands-free drawings myst be darkened in the shadows and lightended slightly when exposed to the light (upper right ..)
Excellent melting of the tones in the clothing and skin... Congratulations Bren!
