A Waltz made for piano, but orchestrated

Hi Mr. Gomes. Welcome to the forums!
I'll be short tonight:

You made quite the orchestration. I am myself not enough well versed on such matter yet to give you proper feedback on it but everything seemed balanced, complete to my ears. I was very convinced with how well you ended the piece.
Keeping the distances, of course, you do have a motif that resembles the intermezzo of the Zarzuela "La leyenda del Beso" (2nd mvt.). And I very much liked that, as well as the piece overall in fact.

In order to get more feedback here from my colleagues, I would suggest you to not just upload your piece. Most people here are used to spammers &/or people that just submits their pieces but don't interact further, even when they meet some criticism, feedback, praise, or anything in return of their comments, so I encourage you to do so (interact, don't just upload) with others' pieces that are seeking for some valuable feedback, causal praise, raw criticism... Whatever suits you best! 

All in all, a waltz that I will share among my friends that's for sure, it was very enjoyable to me.

Best regards,
Daniel–Ø.
