Like her old one better. Never had the impression that Janna was an elf nor should she be one. Didn't think that LoL had elves. Would this make Janna (from the new splash) the last one?
"she looks more like a generic elf bimbo" - the new splash doesn't do anything correct that. She still wears the same amount of clothing. If anything, she's wearing slightly less.
Too tan? She doesn't look tan at all. She comes across as white (Caucasian) without a tan. Perhaps it is just your monitor/graphics card.
The lighting on her face is about the same on both splashes, though the new one has hair coming down over her forehead.
If by an emotionless doll, you mean androgynous, then yes - this new splash accomplishes that. She looks as if she cares about nothing when fighting.
This new splash is a huge downgrade.
She has elf-like ears. Whether she is an elf is not important. Her lore mentiones her otherwordly look, and the new splash represents that way better.
When I say bimbo, I didn't mean anything about the clothing. It's only natural for her to, I believe, have such clothing she has. It goes well with her air-theme. But what I do not enjoy is her, well, makeup. It looks messy. That's what makes her look like a bit of a bimbo. Especially her lips, they look way too dark. Her new glowey eyes also make her look really cool and pretty, really enhancing her otherwordly look. She looks more defined, less messy.
Her ingame model looks too tan to me. Her splash is fine. I think she looks great with really light skin.

So just because she isn't CLEARLY expressing an emotion, she is an emotionless doll? Does '' calm before the storm '' mean anything to you? She looks like she is one with the wind, not '' riding '' the wind.
This is my opinion on the matter.
