Well, Neti... here comes my rating :\
Natural Feeling
With the tiles used, it seems to me like not all of them seem to fit properly. I'm basically saying that the tiles used are used poorly. As I glance closer to the map, I notice something odd. The trees only connect diagonally. I realize you're trying to make a natural map, but this is the furthest possible way of doing so. You need to atleast have a couple of spots where the trees connect vertically. Let's look at the cave entrance now. They usually look really, and I mean really bad if there isn't another mountain/cliff above it. By the looks of this map, you definitely could have done so, *looks to the mountains on the left* and it would have looked a lot better.
Now for me to move onto the diversity of tiles. I only rank on the ones shown in the map... Let's start with the smaller trees. They seem to be used nicely, when not in pairs, which was done multiple times on this map. This should really be fixed, and can easily be done so by a mere two block edits. Moving on to the wild grass. This is done very poorly. Now, if you look at it, the wild grass used does not fit well with the other wild grass, therefor causing an unneeded diversity among them. I would recommend sticking to one patch, or using more than one, in which cases, they match. I'll move onto the flowers now. These are poorly done. Flowers grow in patches, 80% of the time. (Estimate :D) Also, in this map, there is not only a lack of flowers in those patches, but there are a lack of flowers in particular! Meaning, you might want to consider adding 5 more at a minimum. I also notice on this map, you do not use a diversity of normal grass, which is a major turn off for me. Another thing I wish to mention, is that the sand patches do not seem to fit. I would recommend the faded grass pathway. And finally, I move onto the backdrops on the mountains. They aren't done correctly, sorry to say. There are specific tiles for using those. (That is meant for the backdrop going INTO a corner)
Now, I will move onto the positives of the natural feeling. Notice that there is a lot less than there is in the negatives section. This is because people like me seek out the negatives, not the positives.
Well, the shape is wonderfully done. I love how the trees used in this map swerve around, making there never be a dull moment, visually. The mountain shape is spectacular, making it feel natural.
Playability
Playability is the biggest factor in a map, when playing a hack. If the playability sucks, then overall, the map sucks. Regardless of how amazing it looks from a view, if the playability is poor, the map is poor.
Now, I'm sorry to say, your playability is very poor. This map is way too filled with things that the player would have to navigate around, or through. Typically, that would be considered a major flaw to many hackers I know. I would highly recommend removing trees blocking your path, and just leaving the player with a good, clean area to go through. There is still ways to prevent the emptiness, by perhaps adding more pathways, giving more wildgrass, and even flowers and bushes can help!
Overall Rating:
With what is said above, I am giving this map a 5.1/10.
