Here's a piece I worked up for the cover of my portfolio with the heading "World's Tallest Cartoonist" but decided not to use for the following two reasons:

1) While I like the simple triangular composition, the line of figures to the left is too cluttered visually and doesn't read very well.

2) The "conceited" vibe is a little too strong (woo hoo everybody look at me-ee-ee!). Which, regrettably accurate though it may be on occasion, is probably not the best impression to present to prospective employers.
