Well my first vector in Illustrator , is more a work in progress, I have to take several tutorials to achieve what I have in mind. Well, for the first time (I guess) I did something right [If possible, somebody professional can say if is , so far, is good or bad], I've been practicing in various programs (SAI, GIMP, Inkscape, Photoshop) and practiced at it, gave me (I think) a good result.
