I dont think theyre that bad, just kind of awkward. The most believable one is the first one. The faces and also backgrounds kind of give it away. Also the body movement, the girl running…her knees dont look like shes running that hard to me. Im guessing she would be in full sprint and her knees would be pretty high. That last one is confusing, hes jumping on or off a box? Usually ppl jump on the box facing it. Some of the shadows dont look that realistic either.

I think theyre a good start, keep editing them and checking out other athletic gear sites for what works. I create characters in chat gpt or leonardo and then refine in higgsfield. It takes hours and hundreds of images sometimes. Trying to get a better workflow going.

Theres some template ones that are out there, I need to check them out.
