Did awesome with...
The Drums. i don't know exactly what studio your running, however the piano seems familiar. I wouldn't say it's a heavy metal but it definitely sounds cool for something simple like this. My suggestion: try and make your sounds have better quality, it'll help. If your running FL Studio try to master your instruments using the plugins provided or the ones you bought. There are some good combinations to make realistic guitars from simple sounds (if that's what you were aiming at).
Also (if running fl) you could use envelopes to adjust the volume for instruments individually. It was a good song and i liked hearing it (mainly because i'm making a rock song right now). simple things you can add to improve this could include some reverb and and volume control.
Again, i liked hearing this and i hope you continue with this one. Peace yo ;D
