Hot:
Sounds really EDM oriented, particularly pre-drop in the intro and the bass. Sounds pretty good though. I'd say that of anything, the hats and snare are a bit too quiet, and the bass is quite a bit too loud. I'm also not a huge fan of the flute you used. It feels out of place to me. I like the melody, it feels very familiar, but it works. I think at the very least changing it up a bit would do it justice. The orchestral stab really works with this one. I think thats the highlight of the beat. I think above all else what this beat could really use is some soundstage work. Doing some work on panning would do it a huge justice. As a final critique I'm not huge on the pulsing bass. It sounds fine, i think its just a matter of preference. Still overall its a cohesive beat that sounds good, just could use some polish.
Down It:
Simple but pretty nice. I like most of the sound choice in this one. Same thing as hot, however, it could really use some panning and polish. It also feels a bit video-gamey. Not a bad thing, but its definitely a stylistic choice that could be a detriment. The drop with the 808 at 1:36 is really satisfying. The mix on this one is way better than the last one as well. Not perfect, but more than adequate.
SOB:
This is so far my favorite by a long shot. This one sounds distinctly hip hop. I like the panned snare first and formost. The melodies are also nice, and your orchestral stabs, like the first one are on point. The mix is ok, but I think the bass is also a bit loud comparitively to the rest of the instruments. I don't mind where the percussion is sitting as it is now, but the rest could be brought forward a bit in the mix. Doing that might result in need for tweaking the percussion to fit, but I think it would do it justice. In comparison to the other two it sounds significantly quieter to me. I don't think its a case of over all volume, i think that its loud enough in some frequency ranges and not others. My final critique otherwise is that the entire beat doesn't have much for variety. Theres some one shot stuff, but I don't feel like it has defined sections. I think you have something here, but it could use some big changeups to elevate it to something much greater than what you have currently. The same could be said about the other two, but this one particularly needs it.
Having said that I need to get a set of 8" monitors because my eris e5xt's don't accurately portray bass well enough, and my headphones overpronounce it. I used to make up for it with my RTiA9 tower speakers, but It's not a perfect solution to begin with and my reciever for them shit the bed the other day and any time I play an 808 it shuts itself off to stop itself from frying. My ability to hear mixes, particularly with bass has been stunted significantly so take my mixing critique with a grain of salt. Theres plenty of people much better at mixing than I am here anyway.
