This concept looks great, but

1) Using night mode is cheating, because almost everything looks cooler in the night mode. The day mode is and will remain the default, so it's impossible to evaluate design suggestions made for the night mode only.

2) The tricky part of implementing this rounded-corners input field is how the messages are scrolled under the input area. There is the WhatsApp approach of an "invisible straight barrier" (which is lame, but may as well be inevitable), but there could be other more interesting approaches to explore.

A great redesign of an element should take into account how it will work in combination with the existing elements. We'll be happy to award all contributions that are thought-through in this way. And thanks to all the designers who keep sending their work. Together we are making Telegram better (@durov).

Splitting a group chat into subgroups this way could be a great idea. You can instantly see the number of unread messages in all the subgroups and intuitively understand how they work.

Navigation between them is not too easy, however, since side-swipe gestures are already taken for the 'back' and 'reply' actions. Reaching to the top of the screen also might be a bit of a pain, but acceptable overall.

The concept is not entirely thought through though. The chat list shows one new GIF message in "Jeff's club", but opening it displays 3 new unrelated messages in "Offtop". So where's the GIF?

Currently there are too many questions lacking answers. Which preview should be displayed for the group in the chat list – the last message of all of its subgroups? Should opening such a group always take the user to the subgroup with the most recent unread message? Can notifications settings be different for every subgroup – and if yes, how can a user change them? What happens if the titles of the subgroups are wider than the screen width? How do you actually create subgroups – as different group chats that you bind together, or as sections of one group?

Figuring out all such details makes a great design concept, worthy of a prize (~@durov)
