First of all, really nice work. Secondly, the lead feels like it's too robotic. Try adding a little bit of vibrato in, and try adding some portamento to a couple spots. Those two usually do the trick in getting something to sound more natural. Now, as for the sound itself by itself, I would recommend mixing in a completely unprocessed mono saw in the middle, just turn it up to where it's noticeable, but not obvious. Making your supersaws too wide and too huge is a bit of a pitfall, and bringing in some more pure tone in the middle can help fix that.
