From your previous maps, I can say that you've been improving greatly with every map in every aspect.
The only thing that I still see need improvement is that you need to work on your map layouts. Although this still manages to play well, this layout better serves as CTF rather than HTF. A true HTF layout would be something as of HTF_Baire, HTF_Zajacz, or HTF_Rubik, theses are default maps BTW. One thing you have to notice about all these layouts is that they allow fast-paced gameplay and allow many methods of the flag carrier to escape and move throughout the map.
Other than that, this is a solid map. The shading is very well-done.
