Instrumentally; melodically, this is a nice one... it does feel bright and blue, with a sunlight falling through, and I like the pace - like a refreshing stroll on a summer day. But the overall mix feels a little too sharp, and the composition does get a bit repetitive after a while, with no build, or notable change of pace or melody - it's very similar all the way through.
You've got a good melody here, and good instruments, but might be good to work a bit on the structure and evolution of the piece; how to reflect the nature of the scenery you portray. Surely there are subtle shifts and nuances even on a sunny day. And the sound... I wish it was a little softer. It ends very nicely though, with some soft and summery end notes that trail away, like the end of a good day...
Nice to see the structure behind this too, appreciate the YT link.
Keep up the good work!
