Hi Laura.
You're having a go, so fair play to you!
But something is missing in your shots.
Far be it from me to give anyone advice, but I'm going to anyway
The people have ruined the shots. A bit of editing could get rid of them in Photoshop.........
And they are lacking in contrast. Again, easily solved.
And they are just lacking that 'punch'.
Taken from a different angle could have made them much better. Like getting down real low and shooting the poles from their level.
You are almost there in #2 I reckon. If you'd have shot it at almost ground level, it could have been much better.
And they are also not level, very easily solved in Photoshop.
I don't mean to knock your work, and I'm certainly not perfect :bonk:
Just giving you my opinion, and trying to help!
I'm actually impressed with some of your stuff on flickr, and I've added you as a contact.
