I definitely like what you have done. I think my preference would lend towards a more flat design on the shield and I am not sure exactly why but the placement of the words seems a bit off. overall great so far.
About my entries #17 #16 #15 #14 I have created a new concept better integrated in the target population from Missouri. For symbol, I used the outline Missouri state, and part of the USA flag. It is a concept that denotes seriousness, trust, power of decision. By the way, I removed the previous design, because one of the competitors had suggested it. As I've copied the idea with shield. I think I've come up with better idea. Best Regards!
About #18 #19 #20 #21 #22 I have made several versions to exhaust all possible versions. The design #23 is obtained with only solid colors. I hope you like my ideea! Regards!
About #27 #28 #29 I have made several versions to exhaust all possible versions. The letters T and A are cut more straight. I hope you like my ideea! Regards!
#20 is my choice of your most recent batch giorgione. I am based out of Kansas and Missouri though and this only shows missouri as a state would be my only feedback.
