Speaking on animation grounds, I wouldn't consider this design an improvement. As an important character she has to look different to stand out among background characters in some ways.

Nothing wrong with her being chubby, but designing her to look like the side characters isn't the wisest choice with character designs. Not saying she can't be chubby, but she shouldn't be designed to look like the background huskies.

Even husky side characters with more plot relevance and characterization like Nikki, Kaltag, and Star or non-huskies like Sylvie and Dixie have varying designs to indicate an audience these side characters have more importance than the others.

Oh my goood, I love how she actually looks like other huskies now! This is so fricking cute, you did the build perfectly and I love that tail xD Lovely job! She looks utterly squeezable!

She looks just soo cute! In my opinion,She would have been better Chubby Cx**
Great Job Cat!

so poofy! must hug!

awe she cute

Nice! She looks like a big fluffy teddy bear instead of a tooth pick!
Personally I prefer a fuller strong build over a skinny one. Probably not as "fluffy" but she looks a lot more like a husky.
If I were to Give Jenna any build it would be more of a Kaltag style. Then again, I like quirky, tough females.
Anyway, awesome job on this!

So adorable!!

Chris: I think it would be perfect. This is a great picture cat, i really love what you did.

Imagine how the movie would've went if Jenna looked like this.

You know what ? She is way more awesome like this ! I always prefer girls who are not slim x) Nice job cat !
