With photoshop it will never look 100% real, thats when i can help you.
I will build a 3d model of your product, animal, car etc and put it into any photo you would like.
i use advanced 3D programs and super fast render computers which will provide fantastic images.
In Norway where i live i have decorated many restaurants and buildings with this special 3D technic.
Let me hear your idea first and we will make something cool together.
