Hello Asit, thanks for participating in this week's challenge!
The experience you have created seems easy to understand but there are a few things making me question how I would interact with it. The first screen says "Board" and it looks like the app name but it also has a back arrow and tags which makes me think I am looking at search results. The curated galleries also look like a landing page but it also has a back arrow so I am not sure where it would take me.
Visually I think you have created some very clean screens, I worry that the cart Icon and the text may get lost in the gradient you have chosen. I would suggest using all-white text, a solid button, or a gradient that's less drastic so you can use white or black text for the entire thing. I would also suggest giving your labels more saturation. "Artist, size, etc." are all so light I can barely read them. They look great but unfortunately aren't accessible for all users.
I hope this feedback helps! Please keep in mind that my feedback is just a suggestion and that it's always good to get feedback from multiple people.
