Gosh Dangit Moon Moon, we still know it's you with an alt! No but seriously, please read the rules before making a thread, okay? I'll fix it for you this time.

The nose is too square and doesn't have enough/any shading... Also add more detail to the hair to make it less regular, it's pretty much the same throughout.
Looking okay so far, it's just a bit boring.
Edit: Also, add different shades to the hair, sloths aren't just one colour, they are a pretty colourful animal (not colourful, but they have lots of different shades).
