Done for my brother's birthday, from the game that we both played the crap out of.
One comment I got was that this didn't really sound Konami-ish enough, and I can hear that. I wouldn't know how to improve that, so I'm open for constructive criticism.
I see you're trying to go for the Gradius-ish sound here, which sadly I'm not too experienced with, but one signature element of Konami music in my opinion is the staccato bass with the triangle. Don't use sustained bass notes that much.
