Gotta Agree with Ben here, this is a good looking map it's just there are some things which don't work, I'll try to elaborate on things which Ben hasn't already stated.
Brown = Tile Errors, You know the Drill
Lavender = Unnecessary tiles
These fences don't really seem like they belong if the route looked more rugged and abandoned then this would make sense but honestly the route has an Early Game Feeling
Navy Blue = Ninja Bin, Ben missed
Pink = Hard to see Tiles
This staircase I didn't realize existed until I zoomed in on it. Either make it more pronounced or make the top level inaccessible.
Grey = Bad placement
The south one is just weird since you have this very Square like path near a Tall Grass section, divide it some some amount. The one in the north appears to be another entrance to the map, I suggest removing it or changing the surrounding Terrain to compensate.
Black = The easiest Path to get through this route
The problem is it is too simple I mean Left, Up, Right, Up that's it give it some puzzle incorporate the gaps in the trees
Gold = A New Path?
This is just something I realized may work for this Route is that you bend it more, maybe include a Cut Tree and some various elevation levels, maybe extend the little pond you have and make it include another exit to the Map on the East Side. Just make it more challenging in the case of traversing.
