Sketchbook Assignment 6

last sketchbook assignment from my drawing class
had to make a few sketches for our final project to finalize ideas
i decided to go with another self-portrait since i didnt want my final to be a landscape, or perspective, or still-life. but i wanted it to be different too
generally our teacher is REALLY picky when it comes to "fantasy" aka you dont get to
but he was surprisingly lenient in letting me add snow leopards to my sketches since it was "from life" that i observed. i just used a dozen references instead for angles etc

again, these are all preliminary sketches for the final, but which one do you think I chose or derived the most from for the final?
