Not knowing your intended rhythm, I'd bet your dotted sixteenth notes are incorrect; these demand thirty-second notes, which result in a "more correct" notation of the following, which I can't imagine is what you intended:
After hearing your recording, your intended rhythm is:
So as it turns out, your rhythm is actually correct—at least, once you remove the dots!
Otherwise, I'd recommend re-spelling the chord to include a B♭ instead of an A♯. This note is the seventh of the chord, and since the root is C, we prefer to spell it as the note a seventh above C (that is, some kind of B) as opposed to some kind of A.
