Loved it!

Not the first Jack ( at least the 3rd one) but one of my favorite.

great job

Fun puzzle. No guessing required. The right side of his mouth was the only tricky spot, but smile logic easily solved this part.

nice. :)

Enjoyed it. Thanks.

I didn't use smile logic on the left side of the smile (his right, my left), though I wish I had.

Or maybe I did. It's similar.

There were three adjacent columns (9,10,11) left with a "2" to be placed in the same three rows (22,23,24). I knew, of course, that the middle pixels, in row 23, had to be black, but I had to figure out for each column if the "2" was UP (black cell in row 22) or DOWN (black cell in row 24). The row clues for rows 22 and 24 both had a "1" being the next thing in that area, so I couldn't have two UPs next to each other, or two DOWNs. It had to be UP-DOWN-UP or DOWN-UP-DOWN. But there could only be one more black pixel in row 24, so there could only be one DOWN. So it had to be UP-DOWN-UP. After that, the rest solved.

Could be smile logic. It's logic of some sort in any case.

Nice image.

I thought about this a little differently. If R22C10 is black, then two moves later row 24 will be invalid as R24C9 and R24C11 would also have to be black. Therefore we know R22C10 is a dot.

Enjoyed the solve...Thanks!
