Have fun with text
There seems to be some kind of unwritten rule that makes most presenters type their text in a straight line. I do not know where it comes from, but if you only think in straight lines, then you are going to find it hard to design some exciting and interesting slides.
There is nothing in any rules that says you must keep all your text in straight lines. You can let yourself go and have some fun by slanting or tilting you text in your slide.
When using images, tilting your text can really make your slide come alive. But, you need to make sure that the tilt fits in with the image. I would suggest that you play around and see what looks best when you place the text in to your slide.
By using the horizon in the middle of the picture, I was able to place the main text in this slide on a natural slant that fits perfectly with the image.
Always remember that you have the power to place you text anywhere you like in the slide, the only rule I would suggest you follow is that the text and image balance each other, and you can use your own eye to see this balance.
So remember, you do not have to keep your text in straight lines, you can tilt it, you can even make your text vertical. The most important thing is that you have some fun and keep the balance.
