Hello there
Well I will start the review with what I like
First the mixing, you managed a really clean mixing with everything balanced and nothing seems to be interfering with other frequencies. Another thing is the theme, it sounded good with the rest of the song and it really goes well with the genre. The drums sounds great but you can add a touch of reverb so the release doesn't sounds dry.
Now what you can improve in this song are mainly two things: variety and sound. The song felt really repetitive because the theme and the same chord progression was present through the whole 2:21. You can try changing the progression, changing the themes to new synths, adding effects or percussion, or adding a whole new theme. The synths sounded good but you can work more with them. They sound incomplete, try experimenting more with filters and that sort of stuff. Another aspect that you can improve is the mastering in the song it felt a little bit of, but nothing of another world.
Overall a good song with great potential but repetitive.
