Ok... here we go.
So the track opens up with some generic drums. That itself is not a problem, since it's quite hard to make original drums for this genre. What IS a problem, is that you didn't use good samples. So I would suggest searching for more drum samples, that would actually sound good. A thing I would recommend you doing is placing, let's say, kick samples on top of one another (so that they would play the same rhythm). Do that with all drums, in my opinion that is a very good technique when you want to get a sound you're looking for from the drums. Just don't forget good samples. Okay, Let's move on.
After that part there is a piano, but before it there were like some hihats, idk, and they just ended when the piano played it's first notes. What I would do is replace them with some claps and continue playing them afterwards, replacing that piano with some supersaws, completely changing the chords, because they sound awful and making that part into a Big Room (more like Big BOOM) build-up, because that is what Big Room House is all about - BIG, FAT AND THICC BUILD-UPS. Let's keep going.
Then there's the drop(which I can only guess it was a drop, because there are absolutely NO MOTHER#?@*ING BUILD-UPS) . Oh boy is it bad. Yeah, you should really listen to some actual Big Room songs, because this is not what this genre sounds like. Basically make a drop from scratch(intro and outro should be influenced by doing so). I know it says "Big Room/Electro House", but the first drop should really be a Big Room House type of drop. After the drop there are some saws. They sound weird. So weird in fact, that when I remember the track they sound like they're melody has got nothing in common with the one that the piano's playing, although they really are playing the same melody/chords(not really sure xD). I'm not too sure why, but you should still fix it
. Also you should, like, totally replace those saws with some SuPeRsAwS maybe.
Now I want to adress that the mix is quite weird. Here's what I heard :
1. Intro
2. Verse
3. Drop (NO F*%#ING BUILD-UP BEFORE IT)
4. Post-Drop
5. 2nd drop (again, NO BUILD-UP)
6. 3rd drop (wtf man)
7. Post-Drop 2
8. Outro
So this what I would suggest :
1. Make a build-up(already said how I would make it).
2. Delete the second drop.
3. After the Post-Drop make a 2nd build-up that would be longer by like 4 or 8 bars(up to you).
4. After the 2nd build-up put the now 2nd drop (it was the 3rd drop before).
5. Make the 2nd drop have some elements from the 1st drop, so that it wouldn't sound random.
6. Add some subbass to BASSically (hehe) everything.
7. Delete the 2nd Post-Drop and instead play the outro.
Even though in my opinion this track really doesn't deserve a rating of 4, i still liked some of your decisions, like the filtered saw playing in some times on the 2nd drop or the 3rd drop. I know that for you it feels like you have spent a lot of time on this track, but I don't think It was enough. For me, 10 hours is normal to spend on a single track (I probably spend even more since I have so much free time, now that I think about it xd). I don't think you improved that much, but at least you didn't use any of those ear piercing saws...
Now that I think of what I just wrote, this was completely pointless, because this just a tutorial how to make a track in Big Room genre. Or basically how to make a completely new track. Wow, I'm so stupid. Well, I'm posting this anyway, so that this wouldn't go to waste xd. I still hope this helps in the future.
Edit: thanks for clearing up on that build-up situation(now that I understand why there were no build-ups, it seemes like it was really an interesting song :) ). Also I already knew that there were different genre drops, I just forgot to mention that. Oh, and btw, this the first time I am writing this long of a reply, so ur welcome!
