as my first post on this forum : its rendered in cycles using blender 2.73 
Very nice!
Oh! A very cool idea to mix a ‘historical’ phone (I mean the receiver) with parts of a digital phone (the display)! I like these kinds of inventions and design! Textures and lighting are great!
If I zoom into the picture to 100 % there are coming out a bit the edges of the coffee cup on the border. I think with a subdivision of one or two times it looks better. But this is only a small detail!
All in all a very good work!
