Since when was Takeuchi 'highly praised'? I'll give it he has a knack for designing very nice character concepts, but I've yet to see anyone praise him for his artistic skill, even with all the improvement he's gone through over the years.
He's very bad at drawing profiles but good otherwise. It looks like he's improved again for their new stuff, but maybe that's just because they've pushed half of it onto other artists?
I thought F/SN was considered "new stuff", compared to, say, Tsukihime, but I guess it's not really. fate/unlimited_codes is relatively recent, right? Well, in that tag I don't see anything as bad as this, anyway.
