Hello,
This site does offer feedback about compositions, just there is a section for that, where you upload your music and member comment. this way you won't get much feedback. I will comment about your music, but next time, upload your file with a description and we all could help you more.
I think the mix is very clear, even the voice is well mixed, some elements could be a bit louder like that sort of vibraphone, also some more breaks on the beat, specially the hand-clap, also the bass gets a bit lost in some parts, others are fine.
In FL Studio always put a few empty bars in the playlist at the end, to avoid the last note is without tail like your final string.
Keep it on, is not bad.
