These are very good. Most of the others were too dark and some had coloring around the circle which made it look irregular from a distance. Look at the comment posted on the main page and apply here. Also, try putting an image of the USA only inside the circle. Last, lighten the color blue a little bit.
Please look at the comments on the main page about inserting the text we need around the circle. Also, please make the BWMA font a little larger so it stands out more. You could also try white color for the BWMA in #164.
