Good playing
I always loved the Cossack songs from MMIV, which is also one of my favorites in the Mega Man series.
If I can critique, it sometimes it feels that the melody/lead guitar gets drowned out by the other instruments around. Maybe you can beef up the lead a bit, volume-wise, or tone down the rhythm guitars, which is probably the wiser course.
I personally think it would help out this track a lot to have a very clearly-defined melody.
Other than that, this is well--made and enjoyable.
Great job!
