"Overall, the app design looks sleek and modern, with a user-friendly interface. The color palette is well-chosen and gives the app a clean and professional look. The navigation is intuitive, making it easy to move between sections. However, the buttons could be more visually distinct, as some are hard to differentiate at first glance. Consider adding more contrast or a hover effect to improve the user experience. Great work so far!"

Nice UI, I'd like to think that on launching the app the character in the chair spins around, very nice! I'd watch out for the caption fonts though and maybe create a little more contrast between the background and the chair color, since it's a mobile UI, I'd make the book now more centered and a little bit bigger at the bottom, good room to grow!
