For me, that is enough

Alright, let me just say that this is amazing. I absolutely love it.
First, the color on the hair is perfect, though I feel like it should have more light on the top left side, still, it's wonderful and that shine across it makes me smile.
I feel like the right side of his jacket should have more shading/coloring. Other than that, you got the rest perfect. The neck seems like its missing something and its a tad bit pale, alas it's still wonderful. I see nothing else wrong with it.
I like how it seems like the tears are almost glowing, only slightly, but it really brings our eyes to it. Again, that shine on the hair... It really adds some spark to this and I know that I, as well as many others, loved what you did with it. I also like the shading around the covered eyes, the hair shading really matches the area around it.
The smile(?) makes me wonder, is he really smiling, glad about dying, or is it a frown drawn from fear and or depression/sadness. It's some what hard to tell.
I like the rope. I feel like the upper right portion of the loop should be wider, but then again, it possibly being the end of the rope gives it a reason to be thin.
The light is just beautiful, nothing wrong with it.
Over all, there were only slight issues, barely noticeable and not really that important. I think you did an amazing job on this, the colors are eye catching and pretty, the expression really gets you to start thinking, and it's very pleasing to the eyes. Even though the picture is rather depressing, it some-what soothes my mind. Also, the wall is a rather comforting color. This picture is beautiful and amazing and you did a wonderful job. Thank you for making this!
