Wow the aston looks good, very intriguing design philosophy too. This former F1 engineer for mercedes analyzed it if you want more info:
Mclaren looks really nice too! But I think the side pod design isn't as agressive as aston, same as the front wing where aston employs alot of tiny tricks to generate vortices.
Looks like these two teams were the only ones with the courage to show their real design lol. I heard mercedes will do the same and actually reveal their 2022 car.
