Well I liked this on Tumblr, but I hate leaving such long comments on there so I decided to do it here.
This is really amazing work you have done here. You can tell that you really put in the time, effort, love, and feelings in this. And even though you were having a lot of trouble with it from layer mistakes to wording you kept going until it was finished an to the perfection it currently is.
The line art is simple and smooth, and the coloring, gah the coloring, I love it! You really get the sense of the dark room, but at the same time it's not too dark, it's like, (as corny as I can possibly make it sound) that the words that are being said and the bond of the two are what are giving off the light source which really gives the picture a much deeper and meaningful touch, if that was your intension or not.
Even without the quote, this picture is so well done enough that you can get a feel for what is going on, and still catch it's meaning, it's feeling.
You have done very amazing work here girl, be proud.
