I'll leave the technical critique aside as I'm only starting up as a producer, so a lot more people here can give you better feedback than I can on what / how you can improve specific parts of your work at this point.

Regarding your question though: "is this track worth finishing?" <- my take is that it's entirely up to you and how you feel about it. I don't think there is anyone here or anywhere else who can truly answer this kind of question for anyone but themselves.

Most often, I've asked myself that question when I felt a bit discouraged about my progress (not only in music, but in any creative work I have undertaken). Sometimes it was the appropriate choice to keep going on the very thing I was working on, while sometimes it was the absolute best thing to just call it quit and take my learnings from my experience into my next piece of work instead of improving the one at hand.

In the end, it boils down to this: Do you feel you're going to get better, learn more and keep the creative juices flowing if you keep on working on this track? Or do you feel that it's only going to drag you down past that point? Decide accordingly. Your energy is best spent in places where you most get to become better, keep your energy high and be your best self.
