Yes it is. It's not like he's tracing an official artwork of anything.
See, this is why Flag Vandalism topic is on uproar for past several days. Someone desperate for fame (and contribution) or CAN'T READ CLEARLY is in action.

And yes, I'm angry.

I think it might actually be a trace, just because of how out of place the wing looks.

Trace isn't a legit reason for flagging.

Added parent/child relationship, derivative work to child, and reference work to parent.

Also agree with Flandre5carlet in topic #13177/p5

I superposed both pictures in Photoshop. It doesn't seem traced at all, if anything just heavily inspired. https://gyazo.com/4f8523911a27d5f348c53bb0f6cdb630 It just seems like houdukixx really liked the pose drawn by tomoe and wanted to replicate it as closely as possible.
