Ok, now this is the legit spot the difference

Well, this is still pretty easy conidering no background element was included in the 6 differences.

Ok, spotted all 6 differences.

A little hint if you can't spot them.

I found 8 differences:

Three in Minegumo, one in Katsuragi, two in Hatsushimo and two in background objects.

Ah, saw them too now.

I thought there was 6 because of the sole number on the commentary (which has absolutely nothing to do with the number of difference) but it had more.

On Twitter, the artist itself said they were 8 differences.

This is 6 of 10. There will be four more of these, it seems; and they will almost certainly be more difficult than this one.
