Sounds great!A little bit Pat Metheny-ish,but it's all right.The whole thing kinda reminded me about that fingerpicking exercise in E major from Eric Johnson's video.Do you know what I mean?
This particular chord(D add4 with open 3rd string,to be exact - not the whole chord,but just the part of it on 5th,4th and 3rd strings) ) brings back some memories:was it in Def Leppard's Hysteria or in Whitesnake's Is This Love or in both?Boy,that was a long time ago(7 -8 years?)!
You've got some nice sounding chords!Your voicing of Am(m,0,7,5,0,0) wil sound good with a major chord too,try m,0,7,6,0,0.Also, try this for Em7 9 - 0,m,4,0,3,2.
Here is a couple of interesting minor7 inversions:
Am7 13 - (frets starting from low E) - m(muted),0,3,0,1,0
G#m7 9 - 4,m,4,3,0,m
C#m7 9 - m,4,6,8,0,0
