Here's the still for anyone who hasn't seen it yet:
In the picture we have (from left to right) Red Guardian, Ghost, Bucky Barnes, Yelena Belova, and the U.S. Agent.
My thoughts on the costumes:
Red Guardian looks fine. It's not as good as his original suit but I still like it. It feels like Alexei's version of the S.T.R.I.K.E. stealth suit. I can't see most of Ghost's suit, but it looks like it's not in the light grey color it originally was, which is disappointing. Bucky is back with the long hair and looks to be wearing civilian clothes (I could be wrong). Yelena looks to be wearing her Red Room suit and has cut her hair in the style Nat had in Infinity War. Finally, U.S. Agent's suit. It looks unusually smooth (probably from the low quality) and he's carrying his shield from the comics. I hope it doesn't have that stupid "US" emblem on it like it is in the comics.
For my thoughts about Sentry, I hope they don't do what the DCEU did with Enchantress and make him an ex-Thunderbolts member who becomes a bad guy. But we'll have to wait and see.
