Hmm, well personally I don't see her as being a towering giant here, and I don't think I've ever (or at least not often) imagined her as being such with other art either. Also I think this artist did a fine job of capturing her, and the about 6 inches of height difference between her and Chen. Maybe slightly off, but capturing heights and height differences in art is tricky, so I'm more than willing to give artists a decent amount of leeway with these elements. I think a certain amount of suspension of disbelief factors in with it.
Really like Lisa (still do) and JeanLisa ship but when Eula appears, I think EulaJean’s much better
I wish Genshin only had waifu like Honkai. I like Genshin’s story and characters design better
Lisa rather feels like the odd one out here as lore goes, but I could kinda see her do this as an apology for pushing Eula's buttons a little too much for the lulz (which is why the latter would rather not talk to her)...
