edit: So some of you have commented about anatomy problems in this piece. Thank very much for being frank! I learned from your comments, really. I'll try to get the comments fixed some other time
"We should love, not fall in love, because everything that falls gets broken."
I challenged myself today. I usually don't do anything emotional... but... err... yeah. XD
The pose was a pain... the lighting was a pain... placing elements in the right place so that it looks like they are affected by gravity was a pain... everything was a pain in this picture.
About the quote... well... let's just say in struck me (even though I wasn't a big fan of Taylor Swift XD ).
It shows how (lol, i've mentioned their names too much, I have a feeling you're already sick of them) are afraid to fall in love, 'cause sometimes, we could be scared of losing the ones who matter the most.
First of all, I adore the blue background. It accompanies the melancholy and sad scene here. It almost feels like one is underneath an ocean but said ocean is filled with despair and hopelessness. And I also love the lone white light that could symbolize as the only escape from the despair.
Secondly, the characters themselves. The tears from the character of the top fits very well with the emotions of the loss of, what I assume to be, his brother on the bottom. It's almost like he is clinging onto him, even when he passes from one life into the next.
This is my first critique here, so I'm sorry if it's not very good.
Okay, first of I like the idea in general and the quote it's based on, because it makes a very good point and and original idea. Still there are some small things in here that bother me a little:
You mostly managed to do the shading greatly and correctly with the characters. I think the boy's shading is mostly fine and to me it doesn't really need much "fixing". However there are some bothering things about the girl's shading that you should think about. First of, her skirt. While the rest of the shading is soft and really gives the impression that they are falling, her skirt looks a bit too plastic and doesn't look falling enough. To bring that up better you could do some little wrinkles in her skirt. After all, in reality the clothes always have some wrinkles in them that makes them look more realistic. I see that you did a good job with her hair, as it really looks like it's floating, so you could use similiar way with the skirt, to make it look like it's floating.
The second thing are her legs and shoes. In general I think the anatomy and shading in her legs is good, but her ankles aren't very visible. If you pay attention to human anatomy, you can see that ankle is slightly, but clearly thinner than the rest of the leg. And in this picture I can't really regonize them from her legs. Thought this could be explained with the fact she would be wearing too big shoes perhaps, but I still think the ankles should be visible. Otherwise the shoes are fine, except a little bit more detailed shading perhaps would be good, since the work is lineless after all.
But in general the picture is very pretty. Like I already said, their hairs look beautiful and very realistic indeed. Also the backround is well done. It's simple, but the light slowly changing to shadow as they're falling is really soft and nice for the eye. Just some little more detailing with the shadows and good will come.
I'd make some long comment on how great it is but I"ll basically just repeat what some has already said. Still, this is really lovely, the pose is great (though it must be a real pain to do it), love the colour of the background you used, I just love everything in this picture.
