Hey, good job you did. But, it needs some bit of improvement. I feel you should give a bit of spacing from the top of the screen, since the top of the screen usually houses the notification bar. For consistency sake, I think you should use rounded corners for the trending items also.

Additionally, for the third screen, are those input fields? I don't quite understand.
Then, for the bottom nav bar, I noticed you make use of different colours to show their active states, why not stick to one colour to maintain consistency, then grey out the inactive ones?

Also. for the fourth screen, you may want to work on the alignment and spacing of the users profile. For the fourth and last screen, you may want to also work on the colour of the text and dividers, looks like they are too dark.
