That's an interesting set. Very enjoyable to listen in general, but as a long time band member I have a few comments on some of your choices.
Square - I'd go with a little bit more "breaking" guitar sound, not really distorted but not perfectly clean either. Your clean guitar feels a bit cheap. Listen to "If I could be a constellation" (Bocchi the Rock) or "Crow Song" (Angel Beats) for some inspiration on that sound. Drums line is quite boring. Try to use more variety in bass drum part and don't be afraid to accent more with crash cymbals. "Jesus of Suburbia" by Green Day comes to mind for some nice execution of that.
Pigtail Bread - The flute seems a bit piercing to my ears. Other than that, pretty cool track.
Intense Nerves - This one really needs some dynamic variation in the drums. When you play long lines on toms or snare you usually do accents and ghost notes a lot, it's kinda like those action drums in trailers. On the guitar side, here I would actually rollback the gain but use fuller chords. Anime music use min7 and maj7 a lot, but high gain power chords are rather out of place.
all Bread Talks and Just a Normal Day - really great background music, tame enough not to take attention from whatever could be happening on the screen, but interesting enough to be listened to on their own. A difficult ballance to make, good job.
The Holy Bread - Vocals sound kinda dry, I'd prefer there to be some decent reverb. There's a reason why most choirs are singing in churches - good reverb blends voices well, and takes away some harshness. Also, it's a HOLY bread - I'd use the most cheesy, stereotypical church reverb for that :D
Stone Blue Fox - I REALLY like this one, very interesting changes, probably my favourite of the bunch.
Cheery - a great, chill outro piece :)
Either way, those are really nice compositions. For figuring stuff out with drums, study some paradiddle excercises to learn interesting places to accent drum parts. It was a great tip from my drummer friend and it's really worth the hassle if you want to up your game in writing for modern drums.
