I love these, i also really like Banksy stuff.
Yeah he often gets compared with him, however I don't really think he should... Banksy is all about humour + deep meaningful messages, and it so happens that he is an amazing artist and some of the stuff he thinks up is truly incredible.
This guy (don't even know his name) has a clear skill in perspective drawing, if you were to change position in any of those pictures you would completely lose the magic of the art, and some of them you don't even realise how big they are (the one with the "giant woman and the bottle", check how many paving slabs the image actually goes over).
EDIT: See all of his work
here, classic name.
