As far as the layout goes, this is a very nice map, but when it comes to detail, it looks ugly. The bright green texture, glass, and brick texture do not fit at all, and many of the corners should be rounded. It seems like also of the thin ledges were thrown in as afterthought, and they are visually unappealing. Also, it seemed some places were too far away (up a cliff then jump across something, then down a ledge, ect).
Also, your files *MUST* be all lowercase, and referred to in lower case from anywhere in the configuration file.
Though this may be no problem to you, It messes stuff up on other operating systems.
