I love the chord progression. It is nice and simple, well paced and beautiful. The melody flows nicely and conveys that sense of peace.
When I listen to this, I think of the town where I grew up. I see myself atop the nearby mountain after a long day of hiking, sitting next to my older brother. A brilliant sunset envelopes the sky, and we marvel at the magnificence of God's creation. There is a feeling of serenity and security, and I cannot help but wish that those few seconds would last an eternity. For the first time in ages, I feel as though I am alive. I feel genuine joy. I smile.
This track carries a feeling of reminiscence, and with it, bitter-sweetness. It makes me remember the good times, but makes me slightly sad that they are in the past.
You've made a nice little track! It is soothing to say the least. You employed a nice amount of reverb and added some nice touches such as the notes at 1:22-1:23ish. The last rhythm at 2:19 was a good way to end it. As for advice, dynamics are lacking. The song is fairly stagnant in that regard. Employ more contrast in volume and you will reach the listener on a much deeper level. Also, subtle tempo changes would make it sound more realistic. I'm assuming that you are using FL Studio, and there is a really convenient way to work tempo changes in it if you are interesting.
Good job and keep it up! :D
