I think the quality isn't bad...but here's what you need.
I think intros and changeups in the track are a good thing. It keeps it from sounding the same for too long. Also, you should layer different sounds with the same notes. This helps beef out your melodies. Are you using straight hardware or software to make beats?
Listen to this to see more of an example of what I'm talking about...

This is the last beat I've made in a while.
I think that your intro, verse, and chorus should all be distinctive. There are some folks who use the verse throuugh the whole song, but a lot of them can't really pull it off like it's supposed to be.
As for best 3? The new one you did isn't bad, but it's missing what I'm talking about above that could make it a straight banger. I see where you did some changeups but it should totally alter the track and bring it back. You've gotten much better on drums by the way.
First off let me say the remix you did on Hit Em Hard was nicely done. Kill the hi-hats just a little bit and it'd be nicer IMO
Quiet Rage was one I could sit back and vibe to, so that one was a good job too.
There was another one I commented on a few weeks back I think, but it's not on your soundclick now but I remember it wasn't named but it sounded like sniper music....I was diggin that one too.
Fiev.
