Welcome to the PF.

What does the 2nd drawing represent?

Also, please try a bit more to find and post some flaws. After you can post 3-4 more (if there are that many), we may be able to offer some hints or ask some questions. It's important for you to show lots of effort on your schoolwork problems here at the PF. Thanks.
