I think this is indeed more neutral, but I also can't help but think it's at odds with itself. It asserts constantly that Ralsei is male, goes over his appearance, then goes over aforementioned redundant topics before closing it off with wishy-washy sentiments.
On the note of the redundant topics, you mention a scene where Ralsei is called "Princess", which was actually discussed and, for a time, added to Ralsei's page as a title. Ultimately, it was deemed flimsy given Flowery refers to everyone as princesses in scenes before and after the cited scene, that there's now an editor's note on Ralsei's page saying to not add it as a title, at least until the topic is revisited.
The inclusion of "Princess" as an alias is currently being deliberated on in the Discussions part of the wiki. Please do not add it while said discussion is going on. Thank you. [Note: said discussion was already linked by me.]
As for Ralsei dressing in feminine clothing, I don't think this requires an entire paragraph. Mettaton, the Dress Lion (who is seen in both masculine and feminine clothes), Blue, and even Toby Fox himself all point to the fact that anyone can wear dresses regardless of gender identity or expression. This basically just leaves the singular they, which as I mentioned, you then proceed to seemingly point out is not a particularly big deal as Ralsei is still addressed as he/him onward, hence my claim of wishy-washy sentiment.
Again, it seems like something that I think is largely best handled in the personality section. You've made notable improvements, but there's not a lot to actually work off of here for gender identity; as previously mentioned, it just looks like Ralsei wore a dress and now we're giving this cute scene a reading which has yet to receive any confirmation. This wiki doesn't even go over extremely popular theories like Dess Knight or Gaster in the plot for similar reasons: lack of confirmation.
