So you use your hand as a bounce card of sorts, and because it is flesh colored, that gives a warming effect to the tactical light. Good idea. I have a few LED flashlights, one is a Fenix E35, the other a cheaper Ultrafire. Both have a lot of light output for their size, and use the 18650 battery, which I prefer over AA rechargables...because this battery is both lithium and rechargeable. It's also the same battery used in the 1 series Canon battery pack (they use 3 cells).
Regarding my criticism of your shot...it is kind of clear to me that you don't feel I can offer valid criticism of your images. There could be any number of reasons for this. It's also possible that you just don't take criticism well. As far as I can recall, I am the only one on this forum who has said anything critical of the photos you post, so it might not just be all on me. In any case, I will continue to speak my mind and offer criticism if I feel strongly enough about it (to anyone's photos...and I do try to emphasize the positive most of the time, despite your claim to the opposite). As for my own photo postings on here, most got criticized harshly, some were praised. Depends on how good the image was, and who is looking at it (or comments on it), I guess. The harsh comments were toward some of my bird images at higher ISO, done with a more compromised camera than the 6D...and also those were shot through a glass window, so they were not my best work. I liked them anyway though, or I wouldn't have posted. In that regard, I think you and I have a similar attitude toward our own work.
I think you might be overselling my response. I don't think I ever stated or implied that you are unqualified to offer criticism; my point is that if you intentionally use abrasive or even abusive language to make your criticism you are never going to get a favorable response. I (and my work) do periodically get criticized; I've been aggressively attacked in this space. Some of that criticism was (in my mind and in others that defended me) unwarranted; some of it had a lot of truth. While I am initially defensive of my work, I believe I am capable of seeing reason. But when someone is abusive in stating their opinion, I lose respect for both them and their line of reasoning. That is and will be true if it is you or anyone else.
I don't mind if you criticize if you do it professionally.
