Hi MissVirus. Unfortunately, I don't have time to review all of the pieces you asked me to, but I will review the first one. First of all, I like the groovy and somewhat ominous mood. Reminds me of those 90s cop shows! XD There are quite a few good ideas here, and the basic harmonies compliment each other pretty well. I still think you should think about getting some better instruments. There are tons of free ones online if you can trust your computer to not come down with a virus (be careful about that!). You could also eventually make your own. The structure wasn't all that bad, but I think it's really busy a lot of time (i.e., there's just too much going on). Also, you REALLY need to work on your mixing. I'm going to assume you use FL Studio, because if you don't, I'm afraid I can't help you much. Anyway, try bringing out different pitches in some instruments more than others in the Parametric EQ (press F9 in FL Studio. Right click one of the inserts > link selected channels > to this track. An instrument should show up (it's highlighted in the Step Sequencer). Then, on the right-hand side of the window, click the drop-down arrow next to the numbered tabs, then click "Parametric EQ 2." You're welcome.) You should also get rid of all the tones below 200 hertz. If you have no idea what I'm talking about, just PM me, btw. The beats are cool, and I think a lot of the riffs are catchy and show great potential. I can personally see that you have a lot of musical talent, but you need to learn your way around the DAW a little more (better instruments, mixing, etc.). Keep working at it, MissVirus! You have my full support, and if you ever have any questions, just PM me! ;D
