Hi, here are the requested colors. I hope you really like them.
I agree, that your company name is related to Mars, but as a designer I feel obligated to express my personal opinion. My opinion is, that you are a, as stated in your description "We are a boutique real estate firm", which should automaticly eliminate the idea of using cartoon characters, such as martians. Ofcourse, I don't want to disregard your opinion and requests, so I made some martians :) I hope you like them.
P.S.: I should be honest, and say, that the entries of Magnita look very stylish and "boutique". I know, she is a competitor, but this does not scratch the facts out. I will continue to present to you more and more variations, so we can get to the best logo you want.
Sincerelly yours,
Plamen Yanev
