I contributed to Api Junkie's Silverlight Loader project by creating the graphics that relate to the progress of the loading stages. I wanted to create something very esthetic without complicating myself too much so I did the whole thing from scratch in Expression Blend 2.
It's all vector graphics so the main tasks here were moving points around and adjusting gradient fills.

Good things:
I was very pleased with the results that can be achieved by playing with gradient brushes and color opacity. Notice the silky shiny hair, the diffused cheeks blush, the plump lips and my favorite effect: the body's volume. Also, I was able to make the torso, the arms and the neck appear like one whole shape. So besides animating shapes I also animated the color gradients by changing the positions and the angles with the Brush Transform tool.

Not so good things:
Starting with small shapes that I enlarged to animate them made me go back and reposition them in all previous keyframes because they would not stay in place. After I understood that when the size of an object changes so does its center (considered the reference point for its translation) I fixed this by modifying the object's layout width and height to a much bigger size so I wouldn't have to translate the object but just move point by point inside the bounding box. This was the case for 2 of the shapes that make the hair, the arms and the head.

I tried the opacity mask on the turquoise background to create the darkened bottom but it wouldn't show at all when I tested the project. Finally I just used a gradient fill with a darker version of the turquoise on one end.

The picture frame was very easy: I created the top side with the pen tool, colored it with a gradient fill, then copied, flipped and scaled to create the other 3 sides of the frame. Finally, not being completely pleased with the colors I modified the gradient fill in one of the sides, converted this brush into a resource and applied to the rest.
