My take

Not bad. Tone is a little flat and a little more variation is needed so the listener doesn't get bored.

Not too shabby.

It sounded pretty good, it really reminded me of Megaman X5 for the original playstation, it needs more oompf to the song, something a bit deeper in the background to fill the song in, otherwise this isn't that bad, keep up the good work.

Pretty good,

But the main riff just echos into nothingness. Nothing behind it, ya know?
Gotta add something that just harnesses the drums within it, so that they aren't so alone out there like the background riff. Definitely needs some work, but I'm sure the outcome will be great. Good luck with the song!
