Here's a challenge that I think many blenderheads may enjoy!
Recently we’ve fallen in love with ‘isometric’ scenes – highly stylised models, projected at a 45 degree angle with (almost) no perspective. ‘Rooms in a cube’ have drawn our attention in particular, like teenage bedrooms with awesome retro objects, a version of your actual living room etc.
For this challenge, any type of room will do as long as it stays low poly. Let’s say keep it under 15k triangles – which is not super low but it will at least allow you to add some nice details.
TL:DR; design an isometric, low poly room and publish it on Sketchfab with the #IsometricRoomChallenge tag.
