I know this is a month old by now, but I'd just like to tell you that I hear a lot of potential here. I'll just write down some of my thoughts.
The same melody is used pretty much throughout the track, but there are subtle changes that happen quite often to change it up. However, even when you change it a bit, the melody is still playing in the 'background'. I say 'background' because the melody is quite loud and actually takes over the mix, so it makes the changes harder to notice.
There are ways to fix this, the main way would be volume control. You need to think about which synths you want to stick out more than others, and adjust their volumes accordingly. There are other ways too but I'm sure you'll discover them with time.
That's just the criticism part though, the melodies are very nice and you change it up a lot which is really good for keeping a listener's attention. You have good composition and I think if you continue making music, you'll eventually be making some awesome stuff.
Keep it up! I'll be interested to hear what you come up with next.
