My First Sketchup

Hi there, this is my first sketchup, not bad for a rookie. Please kindly have a close look at the model and please give some feedback on the design overall.

Here's my sketch which I decided to use for my first sketch up model. This is because they clearly represent something weird and something unique. The problems I had is that I should have done the shape on the grid and pull the shape. Another problem was that I didn't know to save my sketchup as a JPEG and publish it on my blog.
