In my opinion Irozuku Sekai no Ashita kara turned out to just be an okay show with pretty visuals, and could have been better if its main focus was on only one theme : 13 episodes weren't enough to develop all the things (friendship, romance, drama moments) they wanted to.
Art :
The visuals are pretty : the sceneries are beautiful and the scenes with magic are well done. The colors in this show have quite a big importance and the scenes where they are particularly meaningful are gorgous. My only regret on this is that I find their faces a little weird (their eyes).
Sound :
The OST are not bad, but I didn't hear one that I particularly liked. However, I can say that they made efforts with the sound effects.
Story, character and enjoyment :
This section contains a general description of how the anime is developped, and as such may contains spoilers.
After watching the last episode of Irozuku Sekai no Ashita kara, I'm under the impression that this show was trying to development too many subjects at once, resulting in a feeling that it was all over the place :
Indeed, there are 3 main themes that are easily identifiable in this anime : friendship, romance and Hitomi's evolution.
In my opinion this anime is aiming to be quite 'serious' (you wouldn't take this show as lightly as a romcom or a slice of life anime, for example), and from episode 1 you can already guess that there will be really sad moment near the end. However, Irozuku is only 13 episodes long : it's difficult to properly develop these themes within such a short time and keeping with the high expectations of the viewer. And this is where lies the problem :
*********** if you absolutely do not want to be spoiled skip this part ***********
The final episode contains a scene where it's the time of farewells between Hitomi and her friends. This scene is the climax in terms of feels, but I had trouble to feel the sadness as the relationship between the characters isn't fully developped throughout the season, and thus it's difficult to feel the bond between them because in the end we don't know characters well. Nonetheless, this scene is still quite intense but it could have been way, way better if they properly built the feels up to this point.
Maybe they didn't want to finish on a too sad ending? The rest of the episode focuses on Hitomi who has clearly accepted that she leaved her friends and keeps them as precious memories, and is already taking steps towards a new future for her, where she gained more confidence and is able to fully appreciate life.
The same thing is true for the romance, as it is born kind of out of nowhere (it was not an instant love for the two sides) between Hitomi and Yuito. I didn't saw them fall in love with each other progressively : I'm under the impression that they just admitted that they have feeling for each other at some point of the show. There are others romance in the group but they are so underdevelopped that they are not worth mentionning.
There is also the problem with Hitomi's monochromatic vision that is not fully explained by the end of the series : the source of this is probably a magic unconsciously casted by Hitomi on herself as conjectured by Kohaku. In the end it's finally dispelled, and it's easy to deduce that it's because she finally relearned how to appreciate life.
However we still don't know how it was casted, and why there are moments where it's quite selectively cancelled, like the moment where the fireworks are launched at the end of the school festival : why are the fireworks the only things that Hitomi sees in color at that moment? Shouldn't at least her friend also be, since she mentionned that she feels happy that she could do something with them?
************************* end of potential spoilers ************************
In contrary, the development of Hitomi's personnality from the beginning to the end is quite good, although it feels a little lacking : we witness Hitomi growing more and more accustomed to her new surroundings (and her new friends) and taking more initiatives compared to her old self.
In the end this show still is enjoyable but it isn't as good as it could have been.
