@Krystal - the melody have really nice chords, might be okay if you don't introduce the chords first, just the bells and pads is okay enough, and add some moderate spacey texture background so it could be accurate to the title track. You can also fill the gap between the break and the melody with some drum fills before the melody gets introduced. Overall, nice vibe for the snippet
@Wavelength - Your snippet is okay for a start. Maybe it's a bit too sudden to drop the beat after the break. Try to introduce the vocal chops before the drop. Can't add too much I think since it's sounds okay to me. Keep it up
@Emi - The kick is really good here but personally, I don't dig too much that overly high pitched note kick, could be risking of less energy of the kick. Maybe you could be pitched it down. The melody is okay for me. The second screech you use is nice already, maybe you can just use that. The vibe is alright for me, feels fresh. The mix could be nicer if the reverb were not used too much, either keep the reverb send amount less, the bass could be lower in volume since it could diminished other soft sounds in the mix. Overall a good track, but next time work more on the mixing.
@KRB - The kick in your track sounds not proper for a climax kick, since the energy is really different to your mid intro and outro due to your kick length, but the kick complements well with outro but not at the climax in my opinion. The reverse bass is nice, but not to me personally, I like it have to have more character driven than heavy bass. The lead of the melody seems a bit thin, try to add bit of drive and another layer that handles -1 octave. Overall a good try man, keep on working hard for next track.
@NRx - The vibe in the track really nice, for the silence, maybe could add some fills too for backing up the vocals. For suggestions I would love to hear the vocals have some growly back up vocals. The atmosphere at the break and climax is well done there. The kick is very well done and fits the track. The second break could have a bit of bass so the lowend part of that part dosent feel empty. Great work man
So me and my friend decide to make a duo project for now, to see where we could go together. This is our first take that still in progress. I want to know what I could do to make the change of the kicks i've use sounds not too sudden. Any feedbacks are welcomed
P/S: will be deleted soon to work more on it
but don't know about that lead. It doesn't use the full potential of the melody.

Everything sounds pretty good mixdown wise, I'dd work on the midintro to try to fill it up a bit more with fx and stuff.
Nevertheless, I will start with the fact that I like the effects you used while the kick is playing. Now, the things I would add would be that in all of the breaks you have I would search to find either a nice pad or an evolving fx to go in the background to feel the empty space of the break. The track as it is its pretty nice it keeps its vibe from the beginning till the end but in my opinion it needs some more bits and pieces in the mix to enrich the whole spectrum of frequencies. Lastly, I would suggest adding some variation in the rhythmic patterns of your snare by adding it in when the kick plays along, same goes with cymbals I feel they are under represented in your mix. try adding some closed hats and rides here and there through out the mix. Regardless of my comments I do like your track! 
but I'll try to work a bit differently the next time
