Smooth.
For some odd reason this reminds me of my earlier works -- Melody driven that is. You did a great job at sample selection and how you decided to carry those samples out.
Despite some of the choppiness and muddiness, you have the idea.
I think the only thing to regret with simpler or last minute drums would have to be that their effect withers away with listens. I think this would have been a fine song with just raw melody until you revised it with something more fitting, if you still felt like drums.
