Stunning work; the Hounds of Tindalos are such an interesting, deeply frightening kind of monster (imagine being afraid of corners & angles...), and I like your take on them. This one reminds me of a shoggoth.
Well, if I wasn't afraid of corners and angles before, I am now... Honestly, if this is what a mortal mind can think of when it comes to Hounds, how much more terrifying can the unthinkably REAL ones be?
That aside, I like this look for the hounds. It has less of an actual canine feel beyond the moving on four feet. The more, ah--penetrating design gives it an very unpleasant feeling to look at and frankly this is definitely a design that I would use to describe the creatures in any game I would run. Excellent job!
I love all renditions of the hounds yours is one of the best. I see you have done some work for cthulhu wars. Outstanding would love to play this your work is incredible I can only hope to reach your level
