It's not an unpleasant version. But nor is it particularly exciting.
The playing is fine, and the voice is suited to the genre. But both are lacking expression. I can imagine this song with the guitar doing its relentless thing, but with a vocal that works the lyrics a bit harder.
The overall sound was a bit boxy, which is most likely a function of the room you are recording in, and you would benefit from editing the track a bit, i.e. getting rid of the noises at start and finish.
Edit: you might like to do a youtube search for acoustic versions of The Weight and note how others create interest in their performances.
