Wow, that's a lot of obscurity in one puzzle. Never heard of Saoirse Ronan, Aishwarya Rai, neither Renzo Piano nor the term "starchitect", Tziganes, boose, NTD, a nicad battery. I know Sino- as a combination form but never came across the word Sinic to describe Chinese. Can't figure out what DLR stands for.
Had to dig deep to come with Goshen, Arachne, Oscan and the Anasazi. I recognized the name Scott Boras, but hadn't heard of him in 15 years and forgot that he was a prominant baseball players' agent. Whew, that's some obscure fill!
Since I haven't watched TV in about five years I hadn't seen the "want a Fanta" commercials, so I checked out YouTube. Good God, now that song is gonna be in my head all day.
"Shouldn't be tough", "doing so" and especially "I do care" seem a bit clumbsy for crossword entries.
Aside from a few entries (such as for Knuckles and PartTwo), the cluing is pretty straight forward. I certainly can't fault you for that, though. With so many obscurish answers, the clues needed to be straight forward even on the more common entries if only to give a foothold in the various areas.
I suspect that the "mixed reviews" you received is because this puzzle, as a whole, ends up being more of a trivia challenge than a decoding challenge. In other words, what you've constructed is akin to what late-week New York Times puzzles USED to be like when they were edited by Eugene Maleska. So, your crossword is a bit "Maleskan" (which is not be confused with "mescaline", a very different sort of brain-twister).
That's not to say that it's a "bad" puzzle, per se, but that it's not the KIND of crossword that most solvers these days (especially the ones that frequent the crossword blogs and this forum) enjoy solving.
Well, that's my 3-cents, ktd. I hope it's helpful and that I haven't crushed your spirit!
