I have no idea what I'm looking at!

Me neither. Animal tracks at the bottom? A dog brings you a ball? A bird brings a worm?

Or is that a lobster ?

I think we're looking for the name of a band or singer...
Sun snake paw deer?
Moon stick print antler?

...what you find in the bottom of a junk drawer? (unidentifiable items)

Hm. I can get to 67% with moderate lookahead. This is what I did:

Line logic to 50%.

Edge logic on the 3 in column 20, starting at the bottom.

Line logic to 56%.

Edge logic on the 4 in column 18, starting at the bottom.

Line logic to 66%.

Looking again at the 4 in column 18: In any of the three positions it could go in, column 17 is blank in rows 12 and 13.

Next, looking at the 4 in column 13: If it reaches row 19 it makes it impossible to place the 2 in column 17. So we know column 13 row 19 is blank.

After that I am still finding ways to move forward, but only with very deep lookahead.

Found to have a unique solution by valerie.

As Valerie did,

Edge logic on 3 got me to 51%
Edge logic on 4 got me to 66%

The definition of deep lookahead is still nebulous to me & this is one of those borderline cases but here's what I got.

If C1R19 is black then C1R17 is a dot and C3R19 is black,andC3R17 gets a contradiction.

If C1R17 is black then C1-4R18 are dots creating a contradiction in R16.

Now R13C8 is black as R13C5-6 are dots so R13C7 is part of a 2.

If a 2 is in R15 C4-7 then we have a contradiction in row 18.

R17C9 black creates a contradiction in R15 (C10/C12 dots). R17C11 black creates a contradiction in R14 (C11/12/14 dots.)

Line logic.
