Hey, thanks! Awesome to hear people are still using these :)
I can't really recommend similar style textures, all the replacement packs I've seen go for more high-def fancy-pants realism than these, where fitting in with the original textures was by far my highest priority.
I notice that the original link is broken though, maybe a mod could please replace the download link in the OP with this one:

and the "QExpo Booth" link with this one:

cheers!
