WOW, Lilly. Excellent work. Great establishment and maintenance of mood, and totally believable too. I often wondered, "What did Harry DO for the rest of those 19 years? If he's spent his entire life fighting He Who Must Not Be Named, then after that's all over, what else is left on his bucket list?" But you did an excellent job.

A couple punctuation errors that could be caught with an extra reader (hint hint), but otherwise excellent.

aw, so sweet!

You can write. You have creative imagination.

Good focus on one character, his emotions and thoughts.
