I always thought this scene perfectly epitomizes Cyclops. He can destroy you with a blink but he is waiting and checking. As harrietvane mentioned I think he is looking at the Professor and Jean like “So, should I eff him up or…?” There is something incredibly attractive about a man who knows he can destroy you but chooses not to right away.
I don’t really know what people generally call this method of sigil making, so I’m just calling it “Letter Shaping” because you’re using the basic shapes from certain letters. This is the most common form of sigil making, and it allows the most creative influence. As you see above the sigils are for nearly the same thing, yet the sigils came out completely different. Not because the purpose was different, but because I approached them both a different creative way, and that’s what I like so much about this method. There’s a lot of freedom and personalization involved.
