Greek Alphabet Omega poster sketches

I am learning about digital media. In my class, we were asked to create a poster for Typography using either the Phoenician or Greek alphabet. We had to create three different designs with emphasis on display text, symbol, and texttype. Each poster has one element that's the primary focus and then we have to choose our secondary focus and the the tertiary focus. These are the sketches that I did before creating the actual poster of the symbol text on the computer. It is also an in-class exercise and we have to choose different colours for each poster and print them out.
