After playing the game I must say I like the story quite a lot and the art is not bad for someone of you talent. The character design is solid and the characters are fleshed out enough but not to much. One thing that really took me out of the story was the way that Agnes reacted to some of the event happening in the story, such as when two of her friends just faded out of existence. The reaction of everyone disappearing was more rational and dragged right back into the story. I know ,most likely, that for the story to carry one and for time purposes you couldn't have her react in a real way. Sympathy could be felt for both Agnes and Luna (cool name choices by the way), which really added to the story. Story in terms of length was perfect with some minor details that could have been left out, ending was fantastic to say the least. Though the second I heard car crash at the end of day 5 I knew exactly what had happened. Not that twist wish ending thing though which was a fresh idea other than the usual "coma life" that is used. Not going to lie a few tears were brought to my eyes even thought he ending was a vague hint at suicide depending what your choice was. The over arching theme of seven days is a popular one and implemented very smooth here, used in such a way to convey someone's happy purgatory. One more thing there is a spelling error after Agnes "wakes up" when "girl 1" says "heppened" instead of happened. As for art ( take this with a grain of salt), the bodies and hair are fine but one thing that I think you should work is the eyes. the eyes seem off, I don't really know how to explain it, the best reference I can give to look at is the dance scene between Agnes and Keiichi, there eyes are just... I don't know sorry hard to explain. If the way you do your eyes are your style then leave them, but over all nice art. Nice choice of music in all situations, couldn't have done it better my self. I am planing on playing your other games which I have yet to play, I also notice in the description that unlike your other game this one has no "gameplay". Some may think of this as a bad choice but it's a breath of fresh air for me, not to much to worry about, like how your choice will influence the story. You tell a very good, heart string pulling story. The game did leave me with one question though what was up with Agnes's eyes at the end did she just have "heterochromia iridum" or was that a bloodshot eye signifying blindness? Anyway I am no critic but this is the feed back I think is important, let me know if it was helpful. Keep going and getting better at drawing and writing and you could be making great masterpiece visual novels.
One last thing, sorry. I think that the "woken" Agnes looked more beautiful them the dream one in terms of attractiveness which kind of contradicts the bullies calling her ugly, then again someone else's beauty can be another's ugly. (but that's just nitpicking, well this whole thing is, I will shut up now) 5 STARS!
