iOS Neumorphism Redesign

Trying my hand at this neumorphism trend, would love any feedback!! This was attempt #1, I plan on applying this style to a more elaborate user interface!

I do recognize the appeal to neumorphism, however, I foresee the user interface getting very complicated, very fast (especially with interfaces more complex than the iOS calculator). This presents a challenge with neumorphism to not overwhelm the user and preserve simplicity!
