I don't get why they did the cream belly. The normal Zafara has a yellow belly, so I guess a pastel version would have cream, but none of the other pastel pets take that theme. The Pastel Yurble doesn't have a cream belly, when in his normal version he has a yellow one. Maybe I'm being nit-picky, but this one just feels boring compared to the color combinations of the rest, and the Pastel color so far is severely lacking in the consistency department.
Woodland
I don't get why it's so grey. I know there are some grey woodland pets, but they are much more grey. I can't help but feel like this Zafara is rotting... :/
I don't know, there's quite a lot going on here. I'd guess it is based on some kind of tree but I'm not sure which* - it's not consistently grey enough to be a silver birch. It's unusual and I do like it (e.g. the spines on the back as leaves), but the outlining on the right foot and ears is a bit indistinct.
* Having trawled through some Google images the closest I can find is sycamore - the bark's pretty close but the leaves are the wrong shape.
The pastel Zafara looks like the old old purple Zafara, before the awful orange freckles.
The woodland is a little too splotchy. Dunno what's up with the lineart. The palette is pleasantly grey/brown/green.
