Spicing up the song | Mario - Let me love you

Using the capo in the third fret, it's easy to play Mario's 'Let me love you'. In fact if you don't have someone singing to it, it may become boring.
With my regular guitar I tried to spice up the song a bit. And make it more interesting to play.
The chord-forms using a capo are: | Am | Em | D | D :|
Without a capo the real chords are (+3) | Cm | Gm | F | F :|
Lets see how far I will get with the left.
