Fantasia on a Bach theme - Looking for feedback

Hello @JordiHortal and welcome to the forum!

For someone who has never studied musical composition this is quite good!  And this is coming from someone who loves writing variations and basing my music on themes written by other composers or popular themes from various sources.  I think writing music based on someone else's theme can be one of the most difficult, time consuming and work-ethic challenging endeavors.  I am also a big proponent of using variation technique in all manner of composition, even ones that aren't a strict theme and variations form.

I really enjoyed the musicality and pomp in some places of the piece that preserve some of Bach's characteristic style.  Other spots innovated on Bach and really took the piece in new directions.  Having said that, I will critique your piece by saying that I feel like you might have over-emphasized and over-used the initiating hook of the subject ().  I felt like you could have included some variations which didn't begin with this hook.  Also, you kept the basic harmonic structure of the subject mostly intact.  There were however some sequences where you touched on different harmonies which were welcome.  You also made sure to visit the major mode as well.  Along the same train of thought, I felt like you could have really fragmented the subject more and mixed up the different parts of the subject in a different order creating new melody constructions.  That's probably one of my favorite techniques, because it creates new melodies that still have a clear relation to the original material.  Because, I know that sometimes, inversion, retrograde, diminution and augmentation can leave the listener unable to connect the varied material with the original material which is a shame.  But that's not a mistake that your music make by any means.  The connection with Bach's original subject is clear throughout the whole piece which lets the listener experience the same musical material in a new way and it is a celebration of the love of the theme, which I'm sure was a labor of love for you as well.  Thanks for sharing this wonderful piece, and welcome once again!
