From last year, I was taught that a composition is never finished, unless it's set to fire and disappears in the air. In this case for graphic design, it's finished if I delete my project.
Anyways, I am going to call it finished for now. I know in my heart that it's not finished, and that I may not ever finish it. My reason is that the more I work on it, the more opportunities I can do to this portrait, detail wise or using different letters for other areas in the portrait.
It's looking good, but I know it'll be really something when I push this further after today's critique. So cheers! :)
