Since you want to press the issue.
Though I dont think the image is bad, I do see clearly where it could have fallen below that fuzzy yay-nay threshold of acceptability.
Personally I see nothing spectacular about this image let alone creative or aesthetic.
The armor design is mediocre at best. The feet look like they are attached to the wrong legs.
The blood(?) looks like watercolor stains and smudges. The cross insignia looks like smudged wet paint (being the same color as the blood[?]) on the left and right.
The composition and lighting are unimpressive and weak. The character is being overwhelmed, as a focal visual element, by the dominating textural contrasts of the wall, and that odd contrived apparition-like shadow emanating from the characters foot.
The textures make the character look like a toy.
The stenciled wings are a bit of a nice touch.
I really dont think most people that find this image mediocre at best, and are not shocked by its gallery rejection, would bother to add a negative comment to all the fanfare, simply out of lack of interest or motivation to do so.
I really dont place a lot of emphasis on the mass opinion of quality judging by a large pool of 3d cg artisan/crafters constituted by the disproportionately large amount of amature-to-averge folk compared to the minute number of stellar artists making up the pool. A thousand votes on a truly stellar piece of work reflects a pretty reliable indicator of real quality. Whereas quality judging, from this same pool, on a piece of work that is truly only slightly above average, rapidly free-falls off a cliff into la la land.
Thats my honkin 2 cents worth.
