Melody's great! A tiny bit of melodic dissonance goes a long way. It doesn't quite sound right - that's why I like it. Experiment more with your melodies! (Tiny criticism; it feels a little offset; it's ending and beginning where I'm not expecting it to, but that's not too bad.)

Progression is a little long and it's kinda in pieces. Reduce your long-winded low points, but don't remove them. They're a good tool to build energy for when the drop hits, but if they're too long you'll lose your listener's attention and/or bore them. You seem to have a good ear for electro, though, so that's my main criticism.
You should be a little more careful about your buildups, too. That one at the beginning of the song, I feel, is a little unnecessary, since it doesn't lead to much. Try things out, see what works.

As for mixing, your beat is overwhelmed by your synths. If I were mixing this, I'd mellow out your topmost synth (the one that's rough and taking up the high end and drops out at 4:48). In other words, I'd reduce it's sharpness, smooth out it's high-end. It's a bit of an experience thing, so mess around with your synth to see what works.
Your other instruments are really good, but still overwhelming for your beat, so if you want to try some things, here's a bit of a guide based on what I hear and what I'd do:

Try centering the track around your kick - put a limiter on your master and let your kick hit the top of it (but not going over!) and try to compress it if you can, keeping it right there. Compression is a bit finicky, so do some research or use the presets that came with your software. Compression is important but takes a bit to get the hang of, so you can definitely get away with leaving it alone for now.
(Recap; two tracks. Kick track might have compression. Master has a limiter. Kick track's volume is going up to master's limiter, but not over.)

Next, do some light sidechaining on your melodic instruments. You don't need to go heavy on the sidechaining for these - they're not bass, and your master limiter will help take care of them.
Your bass - bring in something that's going to give you more sub, then put sidechaining on it. Your supersaw bass probably wouldn't need that much for sidechaining, but it might be best to pair it with the sub anyhow, for simplicity.

(If you don't know what sidechaining is, it's... a bit of a thing to explain in a NG review. Look up youtube tutorials! They are a very nice tool, even across different DAWs. To be quick, though, it's a way to lower the volume of instruments to make way for other things - mainly, a kick.)

If you're willing to pay, deadmau5's Master Class is a very useful tool.

You have a good ear for electro! Your mixing needs work, but that's what practice is for. You're already on a good track. Nice job! (I hope this was understandable - DM me if you'd like clarification)
