There all pretty good in their own way...
Number 1 is a little boring but its still pretty good
The reason I dont like number 2 is because it has no great focal because you can't see the bee's face...
But number 2 IMO has the best blending of the background :/ go figure lol
But number 3 looks like a picture you really need to water mark because that is an amazing picture!
Number 4 is also very neat too
