The following is merely a suggestion.
Make the T-Shirt and Shoulderpads a different color. It will add some variety to the figure. You could add a camo pattern to the shirt, or put some camo on the shoulderpads, and leave the shirt solid blue. You also paint the shirt a darker blue (or maybe black), and keep the current colors on the shoulderpads. My opinion is that figures look better when major details are differentiated with noticeable color changes.
Feel free to take or leave the advice. Even if you change nothing, the figure will look great.
Please keep posting your work, as it is very good!
