Yo, what's up? It's birdy boy, poppin' in for another OL jam. Let's take a look...
Overall, this is pretty agreeable, but not memorable enough to make it a favourite. I'll try to explain why!
My main problem with this song is that the drums feel like they're just...there. They play different patterns, but they don't feel particularly essential to the arrangement. I guess what I'm saying is that I could easily see them being replaced without affecting the mood of the song. I will say however that their dry sound helps them stand out from all the reverb you've got on the synths, which is a good mixing decision.
The synths and melodies are all pretty good, though I could've used something more different texturally around the middle of the song (1:47) just to prevent fatigue (the dynamic change is welcome, though). 2:51 to the end is the strongest section to me; it really cements that main "hook" in to your mind, and the lingering of the backing tracks followed by the cutting of the drums and that warm pad make for a solid outro.
To help this song, I would change up the drums to something heavier -- something that complements the big sound of the synths you've used (especially that pad!). The panning you've put on the existing drums is alright, but I feel like it's there to compensate for their lack of power, making them stand out in a different way that isn't as satisfying as it could be.
A extra synth or two used somewhere in the middle of the song as a main atmosphere builder/base would help the song sound a little less generic and add variety.
Melody writing is not a problem for you. The stuff I hear here is naturally interesting, so if you want to improve, focus on other areas first!
Overall, I don't have issue with the mixing, but the arrangement could use some work. I hope you find this constructive and helpful. If you have any questions, or want me to take a look at something you post in the near future, shoot me a PM!
