I like it, but it could take some cleaning up.
I'm pretty sure you recorded this straight from your keyboard, playing it all as one, or maybe it parts, but I didn't pick up any skips in the reverb from the sound or anything on it. For all I know you applied the reverb after you recorded, regardless.
The song as a whole is pretty nice, for the most part it's clean and well formulated, progresses well, but one of the faster parts a bit past 2:30 I can hear what sounds to be mistakes, and if they were an attempt at a tenser set of notes, you might want to revise that a little bit. Like I said, the song itself is great, all it needs is a little cleaning up.
I find it a bit more relaxing than sad, like finding something new and interesting, that place in the middle of the woods, almost a magical feeling, and you don't know what to think of it.
