I liked Ark's recent enough that I tried copying the style/idea. I originally thought he just maneuvered the stock image and added some effects himself, so I tried doing that as well, but with my own twist. It was for practice, since I'm not used to forming sigs using a stock image and no render. After I completed it and showed it to him, I found out he actually rendered most of Angel himself, and thus I practiced in a way that was not used. Nevertheless, I think my outcome was quite good, and I was able to add my own style to an already excellent sig. The only thing I was not able to imitate was the font for "tenshi".
Now that that introduction is over, I took my practice of working with a stock image and applied it to my own creation.
I didn't do any erasing/blending that was needed in my practice example, but I did manipulate the image in a number of ways. I can probably go back and do some smudging/erasing to achieve a different blend result, but I like the way this turned out as it is. My name might need a bit of work, or I can just remove it entirely, but I wanted some comments about stock-image sig-making; whether or not these look good or bad.
