Beautiful image. Contrasts are good, characters are perfectly drawn and very expressive.
The only problem is: I don't know of what this fanart is about. I have absolutely no clue: there's no indication whatsoever, there's no information from the groups you included your work into, and if I google "Cornelius and Gwen", the only result is your work.
Don't take me wrong, I appreciate your work, but it's a recurrent problem with fanarts on DA: no information about the work on fiction they're based on, since the author assumes that everybody share the same references as him. Could you please give us an indication ? Because really, I like that deviation very much and I'm very curious about it!
