Well, I'd have to say a 2 out of 10. The image is too distorted, likely because it was a small resolution image that was stretched thus making it too pixelated, blurry. Also, the fact that the "missing" text it doesn't say a lot doesn't help. I guess the assumption is that whoever sees this image should know who that character is and from what game but not sure what does it mean with the "missing" text.
the background is VERY pixelated, and the text doesn't contrast well, and because this photo is 1x1 aspect ratio and a thumbnail SHOULD be 16x9 ratio, a lot of the top and bottom get cropped. It's visually actually not that horrible, but it still needs work. Need a clearer less pixelated background photo, and I'd go with white text with a black drop shadow instead of black text with outter glow because the text is still blending in with the dark photo. so "Rating" wise I'll say 5/10
