Fugue-Impromptu in F minor (orig.)

[themeandvariation]

This is my latest composition.. The joining of 'fugue' and 'impromptu' may seem like a contradiction, though i contend they work very well together
(anyone interested in a modern composer's take on these old forms  (for piano)?
(This one has a section where it really boogies  

Thanks for listening. Comments and criticism are welcome and appreciated..
