You've got something here
As an incomplete sketch it's actually quite good. I love the usage of techno infused with a bit of piano. Gives it an odd sort of taste that I find I like. Not only does it have a backup bass to help it (while not overshadowing it) you've added a phase overtop of it that brings the two together nicely. I like that you've waited every four beats to hit the phase while the piano is at 8ths. Some people think it's appropriate to do it off beat and it ends up sounding like shit. Glad you haven't done that.
I also love how the deep note on the piano intro became part of the bass during the main line of the song. Glad you didn't just drop it and a very unique thing to do. Well done.
0:40 made me smile. I love what you've done there! Though the high whine at 0:49 was a little overdone I think. Pulling from the piano I think would have been your best bet instead of introducing something new into the mix. I see why you did it though and it works, to me it just sounds awkward.
I really like it and for an incomplete sketch it's remarkable. Simplicity I think is what helps it the most.
Keep mixing and please continue this project,
