Thanks for your submission!
I like the vertical line in
#19I like the shape and color of #20
i like the simplicity of #16, its nice to see some alternates.
#18 is nice because the center reminds me of the rencen building I mentioned in the comments
#16 if the middle piece was rounded it would look like the rencen bldg because i think it is adorned to the sides by square shaped buildings
the fonts look nice
