I made some improvements to most of them. I really like number 6 (the last one on the bottom) but I know its lacking in sloths DNA and almost looks like a super hero, which I didn't intend to do, it looks cool but its not what I want my final creature to be like. Still I like number 4 the best which I haven't improved at all yet. I might just focuse on that one image and develop it. Maybe I should add more fur?
Quick a bit more detailed sketch of a possibility how the face could look like.
