I thought it was fine.
Art was a bit rough and so was most of the animation. Most of that budget went into their anime presentations which looked pretty good.
Faithful to the manga with some nice additions to make things flow better or more interesting. This was a good adaptation.
Plot and development were fine.
It's about kids drawing anime/animation with the struggles and joys that come with it. The neat little tips and tricks about animation, corner-cutting, and narrative devices were cool and informative.
It was entertaining enough. Too bad the manga has no scanlation/translation support as of writing this. I would recommend this, it was unique.
