pic 1- blocky and the sprite makes it even worse 4/10
pic 2- good but i dont like how you ended the right side of the top layer of mountain 7/10
pic 3- reuses a few parts from pic 2 and has a couple of mirrors, yet it is still creative and pleasing to my eyes
7/10
pic 4- i dont know what to say about pic 4...
?/10
Over all, that could be anywhere from 18/40 through 28/40
a very good job with pic 2 and pic 3.
