Not bad at all. I liked how you made the guitar deviate just a little from the original melody, how the piano went along that melody and even emphasized the lower notes, and also how at the end, you raised the melody up a few notes. However, I'm sorry, but I just don't hear this bass line that you're talking about. Were the lower notes just supposed to pop out more here?
Anyways, good work. You might consider hitting up my latest remake of GvP 1.2, which has a tad bit more noticeable bass line.
