Thanks all for your comments so far :)

@Zizka: Ah I see, I didn't know that game but I like them. Thanks for the tip ;)

Look up the power-ups in Contra, you'll know what I mean .

The chrom ebadge is very well done. I'd say either outline all three badges or don't outline any, though.

Quite nice.

You might want to replace some of the colours to give the gamut a higher curve.

Shiny metal is all about contrast. ;)

@Zizka: Contra? What do you mean?

@failureboy: I'll give it a try :)

@adscomic: Ah nice, I guess there are only so many ways you can draw a "winged something" ;) I actually had the Broforce title logo in mind and used it as a weak reference.

I'm sorry, but am I the only one who is reminded of Star Command from Buzz Lightyear? (They look good by the way, I preferebly like the blue and bronze one)

chrome badge looks way better, should you figure out a way to do a new lightsource with the other two by all means do it 

Contra?
