This is another great use of expressive typography. Using the “o” instead of any other letter was the best choice with this word. The “o” in this case gives us the “aw” sound when saying the word “drop” rather than a long o sound like the word “stove”. Great job on this one.
It seems I have a thing for liking simple types of fonts. This type puts the word into use by making everything outside of the "focus" circle blurry and everything inside of it super sharp and easy to read. The circle acts as a view finder for cameras as well when you have to line up the center circle to create a crisp image.
