I know that shadows are not perfect, but it was really hard piece of this work ; ) Maybe sometime I change it.
This bench is my own photo from Warsaw park, and there is the link:

I'm glad you like it :)

Many thanks for the link!
Do you claim some special copy rights for this bench-photo, or am I free to use it in a (non?)-commercial way?

Shadows always are very difficult, I know! Photoshop offers a filter called "Distortion Map...".
Although it's not that easy to handle, it'll reveal quite realistic results.
Google will surely find a lot "phpotoshop tutorial distortion map", and at least one of them will work out fine for your intention!

In case of non-commercial use I can send you this one in full resolution ;)

Thanks, I totally forgot about this feature! I'll continue to work on those shadows :)


I changed the file on DA, I think shadows are much better now.
