I pad Drawing writting

To make my I-pad drawing, I used the opacity at a small level possibly 10 or 12 and drew circles in an abstract manner around the blank document. Then I used the bucket icon to fill in certain places of the circles that were overlapped on others. Now that I have used I-pad drawing I have learned personally for me it is harder to draw on an I-pad than a piece of paper, I have less control on how it looks as a result.
