-
really nice and creative concept there.
considering what others have already said... I have this to add about the footer section
"a doormat is usually placed outside an exterior door for wiping the shoes before entering", now you have a mat that says "Come In" inside the room, but I'm seeing all these creative stuff 'cos i'm already in. Its just does not make right... if its indeed a mat.
Well done The best

I agree with the comments above - the character in the chair looks awkward, the execution is not right. Try some other approaches (photo, new pose etc)
The rest of the site looks great.
