As endings go this one is relatively straight forward. An interrupted cadence (B7 should have gone to E min) with a C/E major chord shape. Fingers 1 & 3 then slide up to G (3rd of E), back down to F# (9th of E) and finally close on a pair of E harmonics.
Laser ahead, always, and make sure to double play the G notes, do not just slide up to them. And that’s it, the end (almost)!
