i really like ur beat! it has a nice vibe .. well done.
but some things you could do better : At first the kick .. sometimes it seems like it was to much low frequenced .. you can hear it clearly at 1:48 - 1:52 .. you shoud take a low cut at 50 Hz

then the next thing .. also the kick... you can hear that the kick is an "one shot" sample because it has a really bad crackle sound in its release .. so you should decrease the outfade time to remove it... or you could cut it manually!

At the end i need to say , that your strings dosnt sound that good in this beat, maybe you can modulate them with a soundgoodizer to get a nicer colour.
