G'day macca,
I think you have some nice shots here... however I also think they are a little tightly cropped (#1,2 & 4)
#3 is my favourite out of this series. Nice position in the frame. I'd just ask for the reflection to be complete (it's missing part of the head) and also the vertical lines at the top are a little distracting.
Hope you don't mind me being a bit picky

that's all just IMHO.
