I saw a comment that said "I was a bit sad the art quality wasn't as nice as the thumbnail" which makes me a bit puzzled.
Yeah, the animation of figures is a bit hazy, rough and always moving but it's so clearly intentional, especially given the amount of detail and shading given to many of the backgrounds, not all of which could have been done by linda-mota. Little things like the face lick and the quality of the lipsync (little things like her mouth at 1:48 especially) demonstrate that clearly this isn't just amateurish work, but someone who clearly knows what their doing and likes this style.
That aside, this is a fantastic animation to go with a song that I didn't like at first but I just put on their debut mixtape thanks to you. Keep up the great work!
