I'd say it's almost perfect, except from the part(s) in which only the drums stays. I'd put some quite low pitched chords in there, to fill the blanks so it wouldn't feel so empty, that does the trick(don't forget to keep em during the whole song)! Another thing is that you you should consider putting some reverb on the short synths you're using. Your synths sounds a lil bit ''dry'', but that's only a matter of taste. Overall you improved! good job! cya!
