I decided to go with Inkscape for designing the vector, if you are using Mac, you have to download XQuartz first in order to use Inkscape
I started to watch some of the tutorials first, then as usual, I just opened the program and started to explore
It was a complete mess actually :D , so i search for a tutorial that teach you drawing with Inkscape, and I find this one made by Ryan Henningsen , and here what I did after that.
