How is the imagery in this essay?

This was what i wrote. The prompt was to think of yourself somewhere, and to describe sound, sight, hearing, and smells.
I am in the middle of a forest, during spring. It is rather warm for a spring day, but in a good way. The gaps in the trees above let in light, that I can see dust motes floating through, and in the semidarkness of the forest, I can see brilliance of the rays of the sun, as it shines through. as it hits the ground, I can see it twinkle off of small, water polished rocks. Next to me, there is a fast moving, yet shallow, and thin creek that seems to go on endlessly. behind me, I can see that the creek is cutting its way through the roots of a tree that is at least the same diameter of a house. There are birds, with a fantastic array of colors, perched along the trees, which would put even Aphrodite to shame. There is a fallen tree that is almost through with its decomposition that puts me at peace, every time I see it. as I begin to walk along, I hear the rustling of the leaves, and overgrowth on the ground being kicked around. The birds, with voices as beautiful as their vibrant colors, begin to sing merrily. The melody of their song accompanies the creek, and they seem to fuse together, into the most alluring sound anyone will ever hear. It is as if the world is problem free, and nothing will ever ail people again. Even the scent of the rotting log seems pleasant, when the natural music is going on.
As I continue to walk along the creek, listening to everything that this forest is offering, I see a small cottage in the distance. Approaching it, with the overgrowth hitting my arms lightly as I walk towards it, the music seems to recede. I find myself entering a clearing in the forest, with the trees slowly thinning, and the overgrown plants start to turn into a well maintained yard. There is a distinct smell, of fresh baked bread coming from this cottage. The smell is very light, but still strong enough that it is all I can smell. The cottage is small, only enough for one room in it. It was of very simple design. behind it, I could see the edge of what seemed to be the beginnings vast garden. I approach the cottage, slowly. as I get to the door, and knock, I notice that at the edge of the clearing, there are felled trees, with some drag marks, making me think that the cottage is new, and made from the woods it resides in. inside, I can hear a grating sound of wood on wood, followed by loud footfalls as the occupant approached the door. as whoever was in there was moving, a booming bark came at me, even though the heavy wood door that made me take a startled step back. The door creaked open, and the man behind it appeared to be a giant. He stood at least 6 and a half feet tall, and was very muscular. In a booming voice that emulated the dogs, he asks “Why are you here, interrupting my supper, boy?”
“I’m sorry, sir. I only wished to investigate, and not to disturb. I have been in this forest many times, and never before have I seen this cottage.” I replied, with a note of panic on my voice.
At first, I thought I was hearing thunder, but when I looked up, and there wasn't a cloud to be seen, it dawned on me that the man was simply laughing. “I just bought this land, and was enjoying my first meal here. come in and join me, won’t you? up until now, I’ve only had Travis as company.” The man said, gesturing at the massive dog at his heels as if he were an everyday sight to a normal person. “Just come in, and make yourself at home. I have plenty.”
So, I stayed, and dined with this giant of a man, who was even kinder than he had seemed. His cottage had nothing in it, except a solid wood table, four chairs at the table, and a bed. The table and the chairs seemed to have been handmade, but, with exquisite attention to detail. The bed was just a cheap, store bought mattress on the hard wood floor.
