First of all, I think you might be overcomplicating things with the tab notation. I don't think its likely that a guitarist who reads only tab would notice rhythmic subtleties such as the 8th rests in the lower voice, if you did intend for that line to have such a "detached" character. I'd consider simplifying the rhythmic values...?
But, if you want to actually notate the piece, there are some general notation conventions to be aware of. One very important one is to show the middle of the measure
(and also the middle of the beat unit, usually)
[*]m.48: rhythmic group for upper voice should be:
Usually, you should try to show the middle of the beat unit, too.
[*]m.57 would therefore look like this, instead of the quarter rest between beats 1 and 2:
If you go through your piece, you will see several other places where these issues occur.
There are also inconsistencies in your 5/4 measures. Are these measures divided 3+2 or 2+3?
If they are 2+3, m.53 could look like this:
If they are 3+2, m.53 could be:
Interestingly enough, the rests aren't consistent bewteen the tab and notation versions! (see m.54 and 57) I wonder why MuseScore did this when you converted the file?
I hope this helps!
