Beginning Modeling Final Project - Blender Logo

Hello. I’m new to the Blender and have completed the tutorials on Beginning Modeling found at the online wikibook Before I continue with the wikibook, I need some feedback from the community about my skill level so that I need to determine my progress so far. Please evaluate my model and these screenshots for the following: 1) I demonstrate an ability to navigate in 3D space. 2) I demonstrate an understanding of the basic parts of a 3D model, such vertices, edges, and faces. 3) I demonstrate an ability to create form in three dimensions. Please assist me with any feedback on my model, keeping in mind that I am an absolute beginner still. I appreciate your help.
