Yeah, the animation can be really iffy early on because of the budget issues, the big set piece fight scenes are where it looks the absolute best because they were the focus and everything else sorta jst connects them. Personally, I think the animation in general does get better as the seasons go on, but that is personal taste, but I do think a lot of the character designs and fights get less interesting after about Volume 3, but again, personal taste.
Honestly, the reason I often bring up Symphogear in relation to RWBY (beyond just watch Symphogear) is the fascinating paralells, being that Symphogear is one of the biggest anime inJapan while bing almost unheard of in the west, shared as lot of the same voice actors in the Japanese dub, hits a lot of the same overall themes and cool transforming weaponry ideas (we even get a scythe girl S2) and follows a very similar tradjectory of barely there budget through S1 and having to pick very carefully where they spent their budget, growing into an absolute spectacle of a show while making it all up as they go (since each season was actually supposed to be the last, except the last 2) but while RWBY often feels like you can see the crack, Symphogear does a fascinating job winging it and pulling things together. I'm not one of the people who say Symphogear is RWBY but better, but they are fascinating to compare.
Also, on meaningful shot composition, one of the most anime anime's out there, Star Driver is just a masterclass in this. It's basically the combination of the teams behin Revolutionary Girl Utena and OHSHC to do an epic find the 4 maidens to release the apocolypse type mecha series, that layers so many levels of weird surrealism, metaphor and unusual important shot composition. It's a wonderful watch for studying more artistic meaningful shot composition.
