I know what you mean, unfortunately I've got no more at the bottom. I've looked at taking a little from the top but for some reason it didn't look quite right, a bit squashed.
I shot this from a car so until they cut the hedges I'm kinda stuffed. Hopefully they'll start topping them soon and I can give it another go. I'd like to get the same image in the Winter / Fall maybe with a little snow.
Love it! Great IQ, and the look on the owl's face is priceless. Love the tree hole it is perched in. I agree with Ofer's comp suggestion, but it seems you have none more at bottom. Still an awesome image...well done! Is the image a bit too green? Here is a repost addressing that (I hope!)
P.S. Your image file is too large, just keep in mind it should be 250kb at most...
