Try and simplify the color schemes. Sometimes less is more I am a little more plain than these colors. Also the first 3 are a bit blocky and the most recent is a bit to cartoonish.
I like the ideas. I'm looking for something more rustic, western, kinda like the examples I attached to file. These are all a little to boilerplate Let the name and the initials stand out more. Not really crazy about the circles. Look at the examples I sent in for inspiration.
