Well, it costed some time - I remember the first version in SZ (dunno, maybe I commented it then) and I can say that you made a really nice progress here. Even when the vector is not perfect (some lines missing and a bit jaggy sometimes), I can just congratulate to your first accepted wallpaper on AP. Welcome in the club :3

WOW! to be your first submission! you did a great work here^^

There are some jaggy parts in some places and some problems with the light and with the tree but you did a great job and i apreciate that.

The thing i love the most is the whole perspective! wow i Like it!
I think its Awesome! Keep up the good work!

Bokura ga ita is a sweet story. x3 i love the scan that you chose to wall and i love the perspective in this. *__* it's even more impressive that you extended the scan. however, i do have several complaints, if you don't mind me voicing them. please take them as constructive criticism. ^^;

jaggedness. @~-J@ i see a lot of pixelly lines, some pixelly to the point of being kinda discontinuous. otherwise your vectoring (?) work is pretty awesome. lol at the colorful outlines! ah, it's a bit of a shame that the tree and the chalkboard text are both kinda low quality. the text is okay, i suppose, but i keep on getting the impression that it's blurry from transformation (ie. scale/stretching). and the tree looks kinda like it came from a screenshot, what with its quality and that ring of orange. :x only if it were cleaner, then it would go nicely with your wall. and the lighting...! don't you find it a little strange that the desks closest to the window (a source of light) are in shadow?

out of curiosity, why is it that the sky is blue (as if it's daylight out) in the large windows but is pink and purple (as if it's evening) in the smaller window on top? :O little details like that make a difference. ;] like, how the chair near the center of the bottom of the wall lacks the third dimension (its thickness). and how one of the metal bars for the chair/desk to nana's right is light gray while the other bars are dark gray. or maybe i see too many minor things upon first view. x__x

the box/shelf thing behind nana: each one in a row look "identical" in terms of the angle at which it is viewed. however, the angle should change, just as with each table in a row. each one in a column should also be seen at a different angle. (if you look at the shelf closest to the left edge of the wall and compare it with the closest table, the perspective looks wrong to me. it appears as if the openings are facing more towards the left than the front like the tables (i'm using the chairs as a reference point when i say "left" and "front"). and it also look like they tilt up from the ground.)

i'm sorry for being so picky. and don't get me wrong. this deserves applause. xD your effort really shows, as does your potential! keep up the hard work.
