Aw yeah, I love little waltzes like this! Really like how you used the instruments here; bassoon and celeste really sold me on the piece early on, and the violin had a perfectly expressive melody line. I think you might have been able to vary it up a bit more by having a cello take the melody once the instrumentation thins out a bit, like a response to the previous phrase (especially because it's hard to hear the flute over what the violin is doing). My only gripe with the ending is that the major 3rd comes in while you're still on the V chord, which just sounds odd - the leading violin goes from [scale degree] 1 to 7, but then jumps to the major 3rd and leaps up to the 1 above, while the counter line does the same thing, but goes from the min3 to maj3 before jumping. It sticks out less the more times I listen, but it definitely jumped out the first time. I also think the 2nd violin should stick to the major 3rd on the last chord, but that's just my opinion. Great classical piece after a month-long break! :D
