Way to waste the last images we had on this thread.
I don't own neither the clover girl, or drossel, so I'll give my honest and hopefully neutral opinion. At one hand, anon is right when he tells clover have a generic design. And at the other, he's wrong by telling that's a flaw.
Quickly: if you can draw the silhouette and highlight the eyes, and still recognize the character, then you have a memorable design. Think on "who's that pokemon?" ad. Quick examples would be Cherno Alpha (nuclear reactor hat), Batman (pointy ears and cape), or even Cattleya (giant tits and ponytail).
However, that doesn't always mean a plain or generic design is actually bad. Plenty of memorable characters had what could be called "plain or generic" designs, and sometimes, quite often actually, less is more. MK Scorpion and Sub-Zero are just palette swap generic ninjas. Nintendo Link didn't had dialogues and his design could be described as "Blonde Robin Hood with a shield and sword". And that's the beauty of it: these characters had a very clear and specific concept, and were designed to transmit it.
I think this Clover succeeds on doing the same, taking a simple, clean and cute design to let the viewer/buyer know what's the idea behind her: a female robot that could be a high tech sex toy, or just a random companion. I love this pic
>>4885825 because she doesn't actually need an additional face to transmit an emotion.
Yup, she may have a generic design. And guess what: she's great because of that. Actually, I would dare to say that's her greatest strength.
