First of all, I think the art isn't that bad, when compared to a lot of shounen/seinen/shoujo/josei/BL I've read: there're series with worse art. Though the art itself could never compare to the stuff in say... Bokko or 7 seeds or Demon Sacred, Son of the dawn, or many other series I've looked at. So, the art is... just fairly acceptable for a shoujo series.
The plot is pretty much standard-fare shoujo: read standard romance with possible rivals turning up in parts of the series, and in terms of complexity, I'd place it at somewhere between simple to slightly complicated. Though, the photography aspect certainly makes it a bit more interesting, I think there're likely at least a few other series which've possibly portrayed this aspect far better(Komatta and possibly a few non-BL series I haven't read).
Some of the characters are the standard-fare noisy/upbeat characters you'd find in Chinese dramas + literature, so they're not very interesting for me but they might be a refreshing departure for others tired of typical "japanese shoujo characters", though I think that Super Girl or Cinema Empire had far more interesting and varied strong heroines and female/male characters. Btw, I thought most of the male characters were quite bland since they seemed to be based mostly on stereotypes and ugh, they might have been "bishies" or "biseinen", they didn't have any enduring characteristics that made them worthy to read about.
Talking about jokes: the jokes between the characters and that the characters themselves make/say are a mixture of interesting and entertaining as well as "seen it, read it a million times" so that's a mixed bag. Some of them were really funny while others were a little boring or even annoying.
So far, I haven't fallen in love with any aspect of it and am still on volume 2 so I can't say whether I'd recommend it to anyone or not. I'll probably update with more thoughts on this.
(Update: Just read up to vol 4 and I'm stopping at this point since the drama and plot aren't interesting enough to sustain my attention. However, for you fans who're seriously into shoujo, I guess it's probably decent enough to keep you entertained for a while.)
