The first shot is obviously, as you say, just a context shot. There are a lot of things about it that make it unappealing.

The second shot however, is very interesting. You've very nicely filled the frame with a very interesting subject. The one thing I would suggest, is to recompose with slightly more of your subject in the frame. Your composition is very interesting, but without the first shot - I don't know what I'm looking at in the second. It would be nice if I could identify the subject of the second without the first - not the whole thing mind you - you've done well to be selective, but just a little bit more.

Good work!
