my first piano piece

I dug through my old musecore files, and found what I think to be my first composition, from four months ago 

Hi @Tunndy!

I think the piece is in Gb major rather than D# major! D# major doesn't really exist as a key signature as it would have contained 8 sharps with F double sharp!

A funny waltz with the running notes figure, and you can definitely extend both ideas!

@Tunndy

what great start to piano writing. Below, you will find feeback, and I hope helps. 

Harmony: 

You've piece in Gb flat major, which is probably a hard key to read (especially if you have double sharps and flats).  I feel if you transpose it G to F it would make easier for young musicians to read.  (Think about that).  

The harmony is entirely diatonic: I, IV, and V.  It would be easier to read if we had waltz pattern was in the bass and melody in treble. 

Melody and motives: 

The motive of chords is nice book end that begin and ends piece. The middle, however, needs a melody. Something that says: Hey this new! 

Form:

As a short piece, it is well done. 

Over all: there are things to improve upon. I feel that is composition has room improvement.  Maybe you have understand core ideas, slowly move to advance ones.
