Good effort, but those horns are more like Texas Longhorns...not quite right. Perhaps a different icon would be better. Font staging is good, so keep exploring western icons.
There is something promising with Entry #24, but the mark looks more like Texas Longhorns, which are not common to this region. On entries #39 and #45 you're showcasing cactus, which don't grow in Wyoming or South Dakota. Perhaps consider a split rail fence in the design or something that speaks to ranch property and or wide open spaces. Thx
