#3 is the stand-out shot by far.
I do not like the angle on #2 at all. The flora on the left clashes with the focus.
The angle on #1 is my favourite, although you should've aimed to have a proportionate side on the left as there is to the right (rule of thirds).
I do quite like the contrast in #1 and #3, the shadows seem to give the images a bit more character. Although, #1 seems a bit over-contrasted.
