Navy (Japan) Shirt

So I made this a while ago and I have been struggling to make it look awesome! I don't know if it's because of the colors, or if it's too light, or something completely different... or maybe all of those things. o - o
Anyways here is what it looks like right now.  I'm basically in the process of making this for my sister who is  serving in the navy.  She is currently stationed in Japan (so jealous!) and I am super proud of her! She seems to be enjoying it as well.  Will (maybe...) post more of my progress of her shirt here.
