I have worked with several KW agents here on LT and in my private business. I have been selected by 19 KW clients here on Logo Tournament.
In addition to my entries above, here are some links to other Contests that I have won (These are Keller Williams agents, in particular, though that may or may not matter) The key is that they are a variety of Real Estate concepts. Feel free to review them to see if any styles appeal to you, and I could model a style that is similar, yet uniquely yours.
I use several lines of thinking in my designs. The smaller "square" designs work great in two layouts. Vertical and horizontal, which is very important. They also make great social network and web icons.
I also make some reference to the "little white picket fence" which is of course synonymous with the American Dream of home ownership.
#65 | #67 - The badge style logo is becoming very popular. It is probably the next big thing in logotypes. This one works great on any background and signage.
The badge is nice. Could you try making the roof shorter and centering the bar that says "Red Shoe"? Also, try the bar bent or curved? if that makes sense?
#84 | This one tells the story of the red shoe while not being too feminine. (which can limit your target audience) It also maintains a bold icon that will be seen from a distance on signage.
#67 | I think this is the strongest of my designs. If you stand back at a distance and view logos on the screen it gives you an idea of effectiveness on a sign. The further you back up from the screen the better you can tell which logos work from a distance.
