Megurine Luka or just Pink Suigintou?

Megurine Suigintou

Almost every character shares some visual characteristics with another. Megurine Luka is no exception. A sharp eye spotted her resemblance with Suigintou and has even shown it in a fanart. You can see that fanart above.

You can look at these two characters and compare them in the pictures below. I can say without hesitance that I see some similarity between those two. And not just some, but quite a lot. Their hairstyles are similar, their faces are similar and they both wear similar accessories on their heads. The question is whether this similarity is intentional and Suigintou really was a model for Luka or if it is just a coincidence.
