I've tried to render the scenes in Blender for better light results, but I'm still not a friend with the program (it means I still don't know how to do it..
) so I had to add some light effects with Ps.Now I'm experimenting with some render plugins (Advanced, Uber, Phong) and with extra lights, but my computer don't like it..
I have 4 cores in my AMD phenom, but (as everybody knows) AMD fries a lot and so my PC shuts down often within rendering because the temperature on cores is too hight. 
No no.. I don't have any big prints of my pictures.
I wanted to know how it looks because I sell my photos for the prints. And a few months ago, someone bought a really big framed print of my "greek photo" (the orange waterscape on the first picture) so I was really curious how my photo may looks on someones wall. 
And the answer for your last question - yes, it is a reall photo from my last summer holidays in Greece.
You can see all my used photos (and some others too) in my deviantArt gallery.
