A day at the National Gallery

So we spent the day at the national gallery drawing. I liked this because I like drawing. and given that it rained pretty much all day its not a bad place to pass some time.
The day consisted of wandering through different centuries of art work and drawings bit of bodies that we liked the look of.

The idea was at the end of the day we would be able to put together all these body parts into creating our own creature/monster/figure.
I really wanted my to have a mermaid's tale. But there are no mermaids in the National Gallery. Trust me, I have looked, several times. The closest I could get was a lobster. I found a dragon and some boats, but no mermaids.
This is my drawing:

Sorry, the picture quality is rubbish.

I'm not really sure what I think about it. but i like the wings, the subtle lobster tale, and all the flowing draping fabric. She looks kind of like an angel or some sort of fairy queen. I'm not sure why I wanted a deer's head in there but with her sprinkling flowers over it maybe she's come from heaven or something to take the poor deer to a happy place? I don't know, I'm not even religious.

Do you think it works as a drawing?
