Nice chord progression. You should try alternating the notes instead of playing them as chords. Like instead of playing them like you are (L for left hand) (R for right hand) LR-LR-LR-LR try L-R-L-R-L-R-L-R In the same chord progression. It'll be Duh-Nah duh-Nah duh-Nah duh-Nah Instead of Duhn Duhn Duhn Duhn. Or if your up for, do those three note chords as arpeggios. Either way. Keep it up.
