You don't mention any other gallery of yours where you might have uploaded pictures like so. Some place you must have practiced.
If you cosplay, you don't mention the artist, who took the picture or who wears the costume.
You write absolutely no description, including this.
And you have this picture witch is truely fabulous. It must have taken hours to make. It is possible that you used someone other's work and this is an art theft. Can you show me your sketch work? A link to another galey of yours? Previous digital drawings???
