Hi !
I would like to add some suggestions as a harpsichordist who is very fond of this style of music. As PeterthePapercomPoser said, the sound itself is the last part of the composition process I think. Concerning your piece, the sound is very good but before considering that characteristic, I think that you should pay more attention to the materials of the composition itself : for example, I have the impression that the rhythm and the melodie of each line seems to lack of coherence. Plus, if you consider the place of the semiquavers, they are placed on the 4th beat of the 2nd bar, which produces a little abrupt effect. Then, If you look the bass line at the 2nd bar, the passage from G to A, you make an avoided cadence which shouldn't be placed in the beginning of this piece, I think. You've got some very good ideas but in my opinion you should pay more attention to the composition before the sound. Besides, what material computer did you use to have sounds like that ?
Thank you for sharing !
William.
