Hello Brena,

Without a reference picture it is hard to adjust a piece
'by memory' or 'until it looks right'
Maybe you could ask a person to take on the pose (Even with clothes on!)

When I first looked at the image it made me think of Ingres.

Please use Google, Picture search and type in this painter.
The pose is not actually there, but you will find a lot of
similar poses. Especially the spine-curve will be helpfull.

You made me smile about the fingers because I could not find
it until a bit later on
I suggest removing the fingers all together. If really needed,
then you should make the pose even more collopsed because
you would really need to stretch in order for the hand to come
that far up the shoulder.

I will be interested to see if you can fix this without a proper
reference. I was amazed that you didn't even used a reference
picture and made what you have without it!

Best regards from

M.E.
