Hi-
I realize the black to gray gradient makes it a bit more dramatic in contrast to the aqua blue.
I like your design a lot. Leave this one alone.
See what you can do w the word real estate font wise and maybe play with shading the sides of the home
or adding color at the windows. Looking for a way to draw the eye in to the design and imprint on a subconscious level so it is memorable.
thanks,
