Hey dude - I made a sig for you. Don't feel obligated to use it if you don't like it, it's cool no worries.
Here's my try at your chop. I know it's not great but I'm still learning. For instance I white-ed out the sky while planning to work on the sig and just remembered to save it at that point. Sorry man!
The only things I would recommend would be a subtle border....and maybe reducing the height of the sig a little bit.
Other than that it looks great. The sun is really bright
Did you use a grass brush?
Adding a border is a good idea! Now that I am at home and looking at it on my LCD it seems a bit washed out looking to me. Seemed so much brighter on my fatty CRT @ work. I did use a grass brush... had to import some foreign grass for the right hand section and then used the colored pencil filter to even both grass sections out and did some color tweaks. Honestly the sun in the corner was a bit of a fudge to cover the grass's imperfection lol
Will work on edits tomorrow - the original psd is at work.
