Dakuwan was last active on the forums in 2017 during T2's remaster release. I've heard he's been active on Steam but from the looks of it he doesn't seem interested in Turok anymore.
Dakuwan kind of jumpstarted my retexture journey. His retextures were pretty yet he never released! It frustrated me to the point I've been slowly making custom retextures via OW, of raptors, leapers, and in the upcoming update, Purlin. So in that sense I have to thank him
