Belldandy is really oversaturated, you didnt really make her brighter, just saturated with more colour and pretty much lost most of the detail in the face
Extraction looks pretty well done, although cant really tell at that res.
I noted the signature saying that the bg was created by Migdalia. While that isnt your name on here i just wonder if thats your real name or whatever. Also i might add that image isnt copyright to Gohda, as he is the director of the anime series, it would be copyright to the original creator Kosuke Fujishima
