Flight of Fancy (for String Quartet)

Hi! I made this short string quartet describing chains of free imagination (as implied by the title "Flight of Fancy") in free form impromptu style...

Actually I tried to make sure all multiple stops (e.g. perfect fifth double stops played like guitar barre (in consecutive perfect fifths or perfect fifths switching quickly from/to other intervals like sixths or fourths), violin triple stops in loud dynamics, etc.) are all definitely playable, and I'd like to ask soon my string major friends to make sure there is no other things technically extremely difficult around the whole piece...

Hope you enjoy this piece, and please feel free to give me any comments or suggestions 🙂

Fun piece! I really love the ending how you introduce the C Major chord. It definitely comes across as a, how should I say it, "carefree" piece. Fits the title.

As a string player there was nothing that strikes me as extremely difficult, all those fifths are giving me a scare but it's just because I personally prefer not to play barres. I think the bigger issue would lie with the cello. They usually have more difficulty playing double stops, but I don't play cello so I'm not sure. Should be fine since it's mostly comfortable double stops like 6ths
