you can download the textures used in these maps on my site with many more unused. ;)
The second map suffered with the same shiney textures, and I felt it was overall not as appealing without the big well made theme of the first map. It also seemed rather boxy.
Both maps have a good solid layout, and use completely excellant textures. I think with a bit more focus on a single coherant theme throughout a map and more time spent on architecture of each area, this author could pump out some amazing stuff. I look forward to more. :D
