Hello YoungComposers

How are we all doing today.
Good i Hope.
Well, two nights ago, i sat at my piano and improvised for a while, which then lead me to this awesome motif, which then lead to a melody and chord progression, which then led me to turning it into a Marzurka which i filmed myself playing yesterday, and posted up to Youtube Yesterday.
Because of the short time i composed this in, you have to understand that it wont be the most tidiest of performances, however, for the timeframe in which i composed it, i think its rather funkalicious.
2 Important Notes before i give you the Youtube link:
1: PLEASE TELL ME IF IT SOUNDS LIKE SOMETHING YOU HAVE HEARD BEFORE, AND THEN BACK IT UP PLEASE...especially if you can link me to a PDF or something to support your speculation.
Im thinking it sounds too much like Granados' Marzurka...anyone agree?
2: Ignore my technique if you are a pianist. It was a simple throw together...most of it is improvised.
The main theme you will hear a tiring amount of times is written down, and the middle section which is kinda of like a sweet variation of the first theme is also written down.
Everything else that fills in the gap is improvised.
I havent put it thru to Finale or anything like that, because im unsure of whether it sounds too much like something else.
