Anyone know the first kanji in the "short" panel? It's bothering me, I can't find it in any Kanji dictionary.

描き - 'egaki'. In this case, egakiwake muri - impossible to draw differently, or something like that. I'm not entirely sure how to translate it.

It's referencing the fact that the hairstyle makes her look like Yorihime (see Mokou's comment) and thus 「描き分けムリ （かきわけむり）」since it's hard to make it easy to tell them apart. I thought the kanji in question was in the "Short" panel though...?

I do find it strange that you couldn't find 「違」in any kanji dictionaries... surely 「ちがう」sounds familiar? :3

Anyway, finished up the translations except for「パネぇ」, which I'm not quite sure what it is. I'm guessing it's localized vernacular, which I'm not very good at. I did put in the t/l for 「違和感」though.

パネぇ, afaik, is a slang-abbreviation for 半端ない (in a "rough" accent, 半端ねえ).
I guess the best approximation is "totally" or "completely".
