This is a wall that i made about a week ago. Np, i didn't use the scan as the bg, i use a photo stock. It took me one day and night to make the photo stock didn't seem too realistic via blur tool and filters. And the scan, the edges are bit rough so i smoothen it a bit, and clean the scan as well. As the sun, i use a lens flare at 90% brightness, and a brush for the light and birds.
I found the scan here at the gallery, but at first it was too rough, so thanks to luciferheart for the suggestions and tips to make it 'smooth'.
As for the sky, it was too pale at first and too bright, so i set the saturation, brightness and contrast MANY times before i get the perfect one.
Hope you like it.
