Things wrong with this image:

rubber arms (panel 1), or magically flying arms, that arm can in no way be connected to that shoulder.
hands have no fingers, recangle hands
misaligned eyes, off-center eyes
generally unfinished, uncolored white spots, etc

In response to topic #11716. All appeals with "part of a pool" should be ignored in this case.

I foolishly realize my mistake too late. What is up with those arms?

The entire pool is below danbooru's and even gaoo's standards. Every page is bad hands/feet, awful linework, bad anatomy and poor coloring with no saving graces.

Being part of pool isn't a legitimate excuse. The flagging menu even lists as a reason for flagging:

Manga: Multiple pages of a manga, doujinshi, or comic that don't stand up to individual scrutiny
