I feel like the author was trying to be pretty optimistic given the setting in Arte. But at the same time the themes for Arte regarding women empowerment felt heavy if I'm being honest. While I honestly agree with that, in the setting provided, that is not true.
True Renaissance era life would not allow this sort of story. Unfortunately, there was less focus on the setting than on the women's power storyline. Arte was less "historical" and more "fantasy" in this sense.
The author also choose to base Arte off of a real life figure, Artemisia Gentileschi, who had a very different life in comparison. The author probably didn't want to show true to life facts for those specific reasons. Still, I would love to see a true anime adaption of Artemisia Gentileschi's life. It feels gritty in a way, like Berserk. https://www.theguardian.com/artanddesign/2016/oct/05/artemisia-gentileshi-painter-beyond-caravaggio
Other than for the themes, the characters come off as boring. Even the drama surrounding Katarina ends up feeling cheap. Leo's old client Ubertino has the least screen time amongst the five characters but he makes a great contribution to Arte's development in bargaining. And since the best thing about this show is Arte's development, he manages to be a memorable character despite low screen time.
Arte wasn't a very good protagonist in regards to how she acted like an airhead and in how she responded to the sexism in the show. Putting in the hard work towards becoming an artist isn't going to change the opinions of others that easily. If that were the case, then life would feel an awful lot like a shounen manga, but this show isn't even shounen to begin with.
Even though animations are not really bad, quality of visuals for both of character models and background drawings are poor. Plus I can't say the soundtracks were good, cause most of the soundtracks are plain and boring. The irony of an anime being called Arte. I can't even say I enjoyed it as much as I wanted to. At the end of the day this wasn't a good historical anime, being one of my favorite genres.
Series I would recommend would be The Rose of Versailles and Golden Kamuy. Both have female protagonists in historical settings that feel awesome and don't have you tearing your hair out in frustration.
