It DOES looks bright, indeed ^^ I have to say that this picture looks simply fantastic. You used the default colours, and a very simple (yet very good looking) dress, so that gives her a divine look. Why would a god care about apperance, after all?
I think she actually looks more beautiful as a humanform! At least how you did it here! WOWZERS!!! ^^ And don`t worrie bout your wings, you draw them really good me think!!! But i know how you feel, im hopeless drawing wings too!!!
It's beautiful, however I don't like her ... attitude. The way she holds her arms makes it feel like she's embarassed. Celestia is NOT embarassed, YOU are embarassed when facing her (And you shouldn't be. Get up and look at me when I talk to you! I'm not going to eat you.)
Quite beautiful, simply amazing.. Welcome to my Fav list, My deviant watch, AND the Equestria Daily #566!!! CONGRATULATIONS!
Also, I would like to point out that while the structure of the wings is perfect, they should probably be moved up just a little higher. But I guess that realy just depends on what your preferences are.. My own Writings place the wings as being right between the shoulder blades usually.
