Group photo in the gym featuring the full group of Avengers actors: Mark Ruffalo standing on the left in green, Chris Hemsworth in the center background showing his abs, Chris Evans on the right flexing his bicep in a Captain America t-shirt, and Robert Downey Jr. (Tony Stark) clearly present and seated in the center foreground in his red t-shirt and white shorts, holding a can/bottle. Seamlessly integrate the bearded man with short blonde hair in an oversized bright blue t-shirt and black shorts (from the second reference) standing alongside them as part of the group. Ensure all 5 men (Robert Downey Jr., Chris Hemsworth, Chris Evans, Mark Ruffalo, and the new man in the blue shirt) are clearly visible and naturally posed together in the modern gym, matching the lighting, depth of field, and realistic photo aesthetic.
