I wanted the door to look high contrast.But you're right,it just looks unfinished.Thanks for the coment.
I love the idea and all in all it is quite great, but some parts of it (the door for example) look like a sketch.
The challenge rules state that the outside needs to be transparent.
Use iaza.com if you don't have a program that can. :)
I like how you reflected the guy in the doorknob!
