I like them. My favorites are the ones on the far left and far right. I think it would do some good to diversify the horror factor; instead of sharp teeth, maybe have a too-big set of human(ish) teeth. This example would be best on the far-right one, since its eyes are already pretty freaky. Making some of them more uncanny would go a long way for you. Looks good, though :-)
Thank you so much that is very helpful! I totally agree! I am still experimenting with 3D modeling so will surly test around as best as I can! Thank you for your time and helpful tips! :)
