Erm. This is the first time I've critiqued, so I hope I can cover everything.
The colors are nice, and the concept is really interesting, but I don't think that it was executed effectively. You have a pretty good idea and the objects involved make for an interesting piece. Unless the title is a misnomer, this doesn't make me think of *cutting off emotions* but rather making your emotions known...I guess? I mean the whole cutting a broken heart, the way it's depicted doesn't really follow the theme shown in your title. the action of cutting out a broken heart makes me think that you're letting it be known that you have a broken heart/someone has a broken heart/ something along those lines, instead of hiding your emotions. Also, for some reason, the colors don't seem to support the theme either, it's kind of hard to explain but *cutting off emotions* kind of denotes a cold person, but pretty soft colors doesn't really follow that idea through.
Anyway, a bit of nitpicking I have is the whole random finger bit. It would be nice to capture the whole hand or at least more of it, because it makes it seem kind of incomplete, which detracts from the overall impact of the piece.
tl;dr: composition/colors doesn't support the theme you're trying to convey. Nothing really strikes me when I look at this, beyond your obvious technical skill.
I like your techniques with the camera and colors, it's obvious you know what you're doing behind the camera. The colors, the lighting, the bokeh (though it'd be nice to see the bokeh being a bit more crisp/defined), is all very very very well done.
The reason why I didn't rate originality very high is because I've seen the same thing over and over. Whether it's the concept you've shown, or the colors/bokeh it's too repetitive. I've seen similar composition/feel all over deviantart..soo yeah.
Highly successful photo. I absolutely love the contrast of the red on blue..The glares in the background add an enchanting effect that enhances your piece. I also enjoy the fact that you used (from what I see, correct me if I'm wrong) surgical scissors to cut the heart..wonderful addition, quite clever.
The only problem I see with this piece in the fact that it could have been cropped a little on the right or it could have used a little less cropping on the left (I think I would want to see the glare so I wouldn't have cropped so much on the left).
I am also contemplating whether cropping out the fingers at the bottom totally would do the photo justice or not. I realize you want to show someone cutting the heart but I would say that there is too little to establish a hand anyways, so either add more of the fingers or completely take them out (it almost distracts from the photo)
all in all, wonderful capture and keep up the good work.
