Delicious, Junk.
In the first one, the rightmost building, it struck me weird with those windows integrated into a roof with shingles like that, i have trouble grasping how that would work, i guess they could be cut to fit, but i figured what kept them insulated was the fact that they overlap the way they do, and cutting them to make room for windows would sacrafice that... Perhaps they are just decoratice, perhaps i am thinking too hard.
In any case, allover great work. Make a graphic novel now please. =)
