Tree clip art made from my drawing

I have two drawings. One of the tree . Complete with leaves and another of the leaf only in greater detail that shows how I want them to appear in the drawing. I need the file to closely match the drawing . I want to be able to use the pic with a background color and the color to be able to pass thru the gaps I left in the tree trunk and also the leaves. The gaps in the tree trunk need to be evenly spaced. I don't want any borders or outlines on the individual segments of the tree. I want to be able to color each individual segment with a different color if I wish. I would like the drawing to be in PNG format.
