This isn't half-bad, but there are some things that I want to mention which no one here has yet mentioned.
Firstly, why do you need an 8va marking in measures four and six? They don't accomplish anything that writing the notes at the octave will not.
What about the lyrics? Did you write them? I won't get on your case about them (as I'm not much of a lyricist myself), but they don't have much of a line scheme, and sound a bit lost. This causes the melody to also sound a bit lost. Also, the word "flower" as two syllables should be written as "flow-er," as that is how the singer would pronounce it.
All dynamics for voice go
above the staff.
You could use more material too. Musically, it isn't really long enough to make much of an impression, or be interesting. Personally, I probably wouldn't sing this because it isn't long enough. A second verse is all it would take to turn this into "Interesting" from "OK."
At measure 40 the Piano needs fermatas as well, not just the vocal part.
This has potential, though. You have some neat chord progressions, and you have a good idea of what the Piano should be doing. These are just some things that I think could use some work.
Not half bad!
