Thanks guys! You're a great help!

Thanks for your reply. I've marked the word "tragedies". Now i just want to cut it out, to either place it somewhere else, or to simply remove it from the picture.

I'm stupid. I used paint. Now i'm using Affinity Designer. Why is it so hard to cut out a f**king region? Why is it greyed out? Just cut that! Can someone please help me?
