This tree ( love trees) my trees in my mind of course...was done with gel pens...a lot of my work is...I have hundreds of designs I have drawn with the gel pens since July 2nd of 2003 the day I stopped smoking...This piece was done with my art professor in mind ....he always told everyone...."no bubble gum trees" So I actually drew on especially for him. Not too good of likeness until I get a better way to get my work on line... digitally enhances adobe photoshop
