Abstract 2D puzzle picture (match the cutout) exercises created

Design details: For a perceptive training for students, I need 30 original puzzle picture exercises drawn/created. Each exercise should contain one "main image" (abstract patterns, ideally resembling biological structures) and five smaller cutouts one of which should be identical to a part of the main image. The other ones should have discrepancies from the main image (some less obvious, some slightly more obvious to create different levels of difficulty). I would also ask you to provide a file containing the correct solutions.

In the attachment you can see a couple of examples to give you an idea of the task. If we decide to work together I can provide more examples to give you a better idea of the required difficulty level etc.

Please note:
1) If we decide to work together, I will ask you to first provide ten of the exercises, so I can provide feedback on the level of difficulty and we can make potential changes, if necessary, before creating the rest of the exercises.

2) Please do send a proposal for the entirety of the 30 exercises.

Target audience: Students
Ideas for the visual style: Black and white; abstract patterns
Preferred colors: black and white
Where the design will be used: print
