Great job.
I lvoe the depth. There is an assload of realism in this. Your art work is evolving quickly, from my looks from your different pieces. This one is very well done. I like how you stayed true to the nurses askew legs and tilted head.
Other people will think the way you drew it is wrong but I wanted to state this to make it clear.
Also the legs are not torn! She is wearing stockings.
And don't worry. Not all the nurses were caps.
