Adobe illustrator is a very powerful application and it's the standard vector application in design field.
& if you are new to illustrator this course could be a great intro for you to get familiar and know the basics of this program form scratch all the way to get you to know about the important tools & panels and the main mechanism of how to operate this application easily and do most of the common regular design work you might be thinking of.
the best way for you if you are completely new to illustrator is to watch each lecture then start applying right away on your illustrator and keep the lecture near by to refer to any step if needed.
hope you enjoy this course and feel free to contact me for any support.
