No, you deserve to be praised. In fact, I searched almost every LiS fan art in this site, I think. And almost other Kate Marsh-fan art can be divided into three types.

1. Doesn't look like Kate. No more comment, amiright?

2. Does look like Kate, but looks excessively sad, so I can't say it's my favorite.

3. Does look like Kate, but looks too happy, so give a incongruity to me.



But Kate Marsh in this drawing really looks like her, and looks 'properly' sad.



Sorry for poor English, but I'm really admired.
