I want to learn to use Tikz properly. I've already created a number of pictures with it, thanks in large part to the help I received from fellow tex.stackexchange users. Thus I'm able to use some of the tools reasonably well, but I have a certain amount of (I think very basic) confusion.

I want to draw a picture of a **** using Tikz. Here's my code. Would you please comment on it, and point out perceived flaws, such as inefficiencies, misused/improperly used commands? Also, I could have used command xxx instead of command yyy. Which option is best, and why?

I ask this question because I find myself regularly correcting mistakes I've made for months even years in LaTeX by randomly browsing questions on here, and I think I wouldn't have accumulated so many bad habits, had I had someone take a look at the ''finished product'' from time to time.
