Overall you have a very nice work started here.  I agree with the first thread that it may be somewhat difficult in measures 3 and 5.  If you wish to keep these measures I would reccomend making the piece harder as a whole.  You need to stop and consider who you are writing this for....kid, teen, concert pianist........?  Also instead of writing out your trill in the second to last measure I would reccomend writing it as a trill with a grace note lead to the next measure then doing a footnote and the bottom of the page indicating how you would prefer it to be notated.  Hope this helps.
