Study No. 1 in C# Minor

Just a mere study for me to analyze the rather interesting keys from C#m to E Major.
More of a prelude; yes, but again, this piece is not so important XD
This took me approximately 30 minutes, to figure out harmonies and weird progressions. A bit rusty in composing ngl, well, I just started.
Hopefully you like it (again not a proper piece but decided to publish).
