Thank you for your design. I like your circle design but the image is a little scary, too strong samurai style. I think you had better change the font and sord and helmet milder/softer design.
#50, 52, 53, the flag design in the middle is not good in Asian region/area because this reminds those people the previous war. Because the Japanse Navy used it and this is the symbol of the Japanese invasion to those countries.
