I really like these small sculptures. The things that stand out to me are:
1. The almost exclusive use of standard bricks. I enjoy seeing smaller models like these that rely on the skillful use of the standard brick.
2. I like the well placed usage of the slopes and the plates. Their small amount of actual variation from the standard brick adds a considerable amount of interest to the model.
3. The two models themselves are essentially the same, but with the variation in color and the placement of the bow (Tie and Hair) a unique effect for each is achieved.
This is very good work. I will be showing this to my daughter as she develops her Lego skills. (See her work under the "Children's Models" section of my MOCpages area)
