This is quite a lovely orchestral piece. The clapping makes me think of it being like part of a dance, which helps with your description of wanting it to sound more happy and upbeat. I am also quite impressed with the musesound quality. One particular highlight for me is the instrument change-up at 2:36. That reed instrument sounds so clear with really beautiful runs. I have recently played Fire Emblem: Three Houses, and there are several cues while calmly exploring the monastery that this reminds me of. I think it certainly fits the category of a sunny spring-time fantasy day. Good job on this and thank you for sharing your music!
