#1 is probably my least favourite of the three.
Some nice shapes almost abstract but I don’t find myself wanting
to linger at it.
Maybe the tree in the bottom left hand corner is distracting me but
I’m not sure.
#2 is my favourite.
Lovely colours and the silhouette of the top half of the tree looks well against the blue sky.
I think you could remove the bit of an adjacent tree that is jutting into the top LHS of the frame.
The lower part of the frame seems a little muddled to me and the various dark features hide the
shape of the tree trunk.
Maybe a lower or different viewpoint might have allowed you to show more of the tree trunk
with the sky as a background.
#3 is very nice.
I do feel that is is a little tight on the subject but I would not be an expert on this.
