Having sparks of creation and imagination upon viewing another work or even the smallest factor has not been a problem for me. My lack of talent, patience in my art, time, and having it done in a professional and decent looking way/style that has yet to appear to me in making sketches is another that has me feeling that it might never come about (plus I have about 20+ other ideas as well before it and more pop up each day/week). I could message you or comment here of my idea if you are interested (so at least also if never made on paper visually it can be imagined but the tale itself for others to enjoy in some form).
Wrong is in the concept. Its a little hard to explain what I mean here, fortunately the author got it.
I think it can be described as wrong as something that should not exist. Although I don't mean that completely literally, I am not offended by the picture and found it quite amusing. But the reason for it being amusing is because of its wrongness.
The very concept of Raven dressing up and spreading smiles is absurd. So completely contrary to what we know about the character, that to see this image is strange, it just doesn't fit in our brain. Not C'thulu level of wrongness, but it still doesn't fit in our brain because of what we know about Raven, and this being so completely contrary to it.
