Hi sketchie105,
The “Work” section is a grid presentation while “Prototype” section is drop down and “Digital Sketching” switches to a sidebar menu. I think one format should suffice. Looks like you’re using squarespace so that should be an easy fix.
In your Work section, both contents of ABCs of sketching and weapons of mass destruction can be added to your "digital “sketching” category, if you were to just rename that to “sketching” and provide two grids section, one for hand sketching and another for digital sketching.
Keep up the good work & best of luck!
