This is looking great! The foreground vegetation, especially the grass, looks really realistic, and the lighting is nice as well. I feel like a little more time spent on the creek's banks is needed to bring that part up with the rest of the image. As for uploading the walkway... we can only accept 100MB uploads right now. I changed the settings to be able to accept a file that large, but I might need Oshyan to go into the PHP config file and raise that limit too. Give it a try, but if it doesn't work, it would be great if you could compress it down to 100MB.
