You've got some skills, the only thing id recommend (which is a problem I contend with as well) If you can throw a slight gate on the guitar, just a slight bit. . there is a tad bit of that dam buzz we as guitarists tend to just tune out because its so often ever present. But its a nice soothing jam all the same.
Letting the notes hang around 3:40 give your phrasing a nice David Gilmor- esque feel which is a great approach.
