Combining Photos

Design details: I have a quick design job that just involves choosing some photos in a file that I will give you access to and using photoshop to combine them and soften the edges (see links below for examples).

The Job:
I'd like to make 20 banners, where each banner will have 3-4 photos in them. You can choose the photos that you'd like to combine together from the folder I give you access to.

There are four themes for the banners to aim for (i.e. 5 banners for each theme):
1.) Science/Research
2.) Artists
3.) Art-science collaborations
4.) Disabled patient-advocates and volunteering


Context:
Art-science charity that works with researchers, patients, and artists to support people disabled by brain or spinal diseases.
