is this belldandy's mother?

I think it's her grown up self.

Bell looks gorgous in this picture

leand me your tears....

"I couldn't bear what had happened.. so I locked you away deep in my heart", something like that, a very beautiful moment

Oh, Belldandy looks so motherly in this picture.

Finally the little Bell sees some light..
She was so sad and forgoten.. ;_; ;_;

"Give me your sadness, and I will return to you everything I have. Come and let us walk the future together"
I love this scene very much; its kind of like where you finally come to terms with yourself and is willing to put the past behind you, accept what happened and make the most of the future. Excellent screencap!
