I fully denounce & despise the harassment.
That being said the reasons she is being focused on are...
1.) Her features are rather old and strong for Starfire who traditionally is severely soft faced & adorable.
2.) Her outfit design is arguably the most divergent from the character, the cheapest looking and unquestionably the biggest disappointment visually which is genuinely baffling considering how nearly perfect & well crafted Robin, Hawk & Dove look. The wig especially is trash.
Like would the following in dark crimson (and longer) really have been that bloody hard?
3.) Her getup GENUINELY looks weirdly prostitute-ish. Not because of the cleavage because believe me I strongly want Starfire to be sexualized but because of the fake ass wig, the random fur coat, the lack of ANYTHING that makes her look alien or unique body wise, outfit wise or technology wise.
90% of the complaints would stop if they just officially state that she will get a faithful design later on and the CGI isn't done or something. The fact that they haven't suggest this is really what they intended to give us.
