Excluding the cliffs you have at least 7 tile errors. 2 of your 4 'sand puddles' make no sense and should be fixed and/or removed. Personally, I believe there should be more landscape variety (specifically concerning grass/foliage) given the layout and context of your level.

It's not a terrible level or anything as a whole though. In fact, it looks better than a large portion of what is commonly found on classic servers (whether or not that's a good thing, each of you can decide for yourselves).
