Good concept, just need to work a little bit into the graphics. Right now, the letters are too smalland the negative space is too strong.
Keep working on it, it has potential!
I would try to work on the composition more. The two building elements, coming in from the corner and bottom of the righthand side could be moved around.
This has potential. Maybe you can also play with different colours (instead the black backround) to make it more pleasant.
nice work, the black and white one is much more powerful, the first one should be just the opposite site in black and white (sorry, I know too late )
