I like design with the 4 small boxes in the M best.#2 and #3 Now that I see it, I don't like the green and blue together so lets try all blue with the greys or all green with the greys. drop the LLC and change slogan to Shopping Center Investments
Drop the LLC from name on all. on #8 and #11 the light green and light blue on the 2nd line does not quite do it for me. I'd like to see how it looks in another color (black maybe?) that makes it pop a bit more.
It would be interesting to see what it looks like if where the M comes together, it looks sort of like a street. it may look really bad, but please see what you think.
I thought, dark green combining with black and grey as accent is good. But If you would like any further changes i made, please just let me know, thanks :)
