#1 is ok, but not enough color- would like to see a star or luminary symbol to punch it up a bit
#2-like the colors, but might not go well with the Keller Williams colors which are a dark red and black, like how slogan in incorporated with logo
#4 & #5-like the text and the star for the "i", but not the house in the circle
#6-like it better than #4 & #5, but might like to include the slogan
#7-Great for Colorado or Wyoming, but doesn't say TX to be, especially the Houston area, there really are not any mountains here.
#8-like this logo, but I would like to see it more incorporated with real estate, something is telling me it looks like a lighting company
#10 & #11-like the general concept of these logos, would like to see it in other color variations, especially background colors
