Hey there cat planet cat planet!
I tried to do as you folks suggested, I hope I did right. Made the girl less of the focus and more of just a wilted flower hanging off the vineponytail, made the eyes a bit more standoutful, and cleaned up the lineart.
Beedfack!
Ruckechoo777 - It's coming along, but I'll agree that your choice of distance may be a bit of a hindrance. My only real suggestion for now would be to pick a specific animal to use as a reference, because right now it's hard to tell if it's supposed to be a cat, dog, rodent, lizard, etc. You have a lot of flexibility to move in terms of the animal, so you've got some real nice creative potential available there.
Chornthild - I like where you're going with your design, no one's really exploring the actual plant side of its growth, so I'd say your design is quite a great point of view. I don't know what advice I can give, I'll probably offer some once I see your next incarnation of it.
Birkal - I like your design, and it's adorable. My only beef with it is where you put the detail. Your big thorny backbowwings are kind of becoming a bigger focal point than the face. I may suggest making bigger eyes like the other guys you see around here, that should at least help to remedy it.
CitterRat - I'm sorry I can't mess up your name without calling you a rat. Your design is pretty cute, however I will say that the similarities to an adult woman kind of seems like it's going the opposite way you want to. I love that bonnet and you should keep it forever because it's incredibly cute, but I'd suggest tweaking the anatomy to be more childlike.
Yilx - Those are so incredibly fucking adorable I love them and I want them forever. I'm not sure which I'd suggest, or if I'd suggest a fusion, but that ball one is also an awesome creative approach, instead of the standard humanoid designs. However, I think if you do choose the seed one, perhaps giving it a little bit of a leafy mini-dress or little nubby arms could make it closer to Necturna, because it kind of looks like there might be a middle evolution if you choose that one as-is.
Noobiness - I really love that whole sundew approach, however I feel the way you've done it is a bit distant from Necturna. The sundew pictures I saw on google kind of reminded me of the mouth of the flytrap, so maybe if you used the flower in that style it could look way past cooler.
MLaRF - The vine's head on top looks like it has a mustache.
