Is that really the sort of playing one usually hears to accompany drinking and talking where you are, or is the title tongue in cheek ? I don't think I'd be terribly interested in drinking and talking if I were at a social occasion and you started up with that sort of stuff. Anyway, titles are to some extent a prison for the listening mind.
I have never thought improvisation should imitate compositional structures, but is better when it creates its own form dynamically, after the manner of a mathematically chaotic feedback loop. Frequently, improvisation of this latter type tends to be about moments rather than a broad conception. Your main strength here is coherent, meaningful phrase articulation. It is easy, once we have a bit of technique and vocabulary, to pour forth cascades of sound which say very little, to play notes rather than music. A lot of famous players actually do this quite often, I think, but we shan't enter that argument here.
While listening to this, it struck me that the reason I hear music and not notes with you is your natural affinity for a certain type of romantic phrase. Regardless of overall form and broad considerations, the listener is keenly aware that phrases of cogent romantic meaning are being uttered. This is by no means the case with all improvisers and, dare I say it, with many classical players. A series of transporting moments, even syntactically unrelated ones, is a perfectly valid form, it seems to me.
You could possibly try making your passage work more heterogeneous by adding or subtracting notes, or grouping them in sections whose cycles are asynchronous with whatever else is going on. But then maybe not - you might end up sounding like me, and that wouldn't be your piano personality.
I enjoyed the patches of double notes; if you can play them well, why not ?
