I googled for a tutorial, a simple one, on how to create vector images using Adobe Illustrator. The version I am using for this vector art is CS3. According to Illustrator Tutorials, this vector art is one of the simplest and easiest to create but I don't know what happened to me; I was complaining to myself and to the software almost all of the time. One of the reasons I could possibly think why it took me so long to create this thing is that I am a newbie in Illustrator.
I was so exhausted after I finished creating this art. Then I asked myself, "how do graphic artists do similar stuffs?". Some of the vector images I saw are even far more complicated than this pathetic and fake-looking pumpkin.

The finished product of the 30-minute vector art pumpkin.
