Nicely done. The neumorphism style works really well when used in context and this is a great example. I really liked the muted colour scheme and simple fonts which fit the neumorphic design style perfectly. There were a few places such as pop ups and the footer section which were inconsistent with the overall theme but nothing too serious.
The only other thing to look at might be the paragraph line spacing for mobile devices where the font is a little too spaced out but I suppose that's more of a subjective thing. Overall, its refreshing to see a design that's a bit different. Keep up the good work.
