I need 6 images that will appear across 6 PowerPoint slides.

Good afternoon.
I attach three of the six images. There are three more but I could not submit them in one go.
Why need is these images to be done in a style that is consistent and can be dropped onto a PowerPoint slide.
When I say a consistent style I am specifically referencing the colour, the type of text used and the type of images that may be incorporated. I am using Gill Sans MT 24 as the font on the rest of the slides so this needs to be considered also.
