2, 4, 6 and 7 do absolutely nothing for me I'm afraid.
1 I like but would have liked for the insects head to have been in focus
The images overall are good but all lacking "punch" - like a lot of people would look at them and go "yeh they are nice" and carry on and not take a second glance. Do you know how I mean?
Theres no specific way to do this as its different with every image, but for the most part they look very flat, and bland in some cases.
Keep it up though, they aren't bad at all!
