Firstly, the suit Barry Allen is seen running throughout Central City in is the same attire we saw the Scarlet Speedster wear in Justice League - potentially meaning the film was keen on using the same suit - and might I also add it can be seen causing much destruction while in use.
Moving on, what many of you will come to find interesting are the several different takes the film originally had on amplifying The Flash's signature lightning-speed trail he creates when he runs.
The gallery of concept art offers a wide array of different concepts - after images, electricity, and huge blows of wind behind The Fastest Man Alive - all initially conceptualized for the Scarlet Speedster to give him his iconic speed trail signature.
Lastly, new concept art for the speedforce - The Flash's main source of power, has been released as well - showing diverse, unique, and artistic designs to blow an audience away.
Unlike to what the The Flash series had done - showing The Flash running through a narrow blue path, the film was set to present the speedforce in a much more "weird-warpy" setting.
The colorful speedforce path The Flash is seen running through in the concept art is a lot similar to that of Spider-Man: Across The Spider-Verse, as you may recall the "orangey-reddish" setting the film used when displaying multiversal travel.
Another piece of concept art shown depicts a more "temporal" design for the speedforce - much reminiscent to how Zack Snyder's cut of The Justice League showed Barry utilizing his power - surrounded by black and blue energy with a finish-lining flash of light at the end.

Worlds collide when the Flash uses his superpowers to travel back in time to change the events of the past. However, when his attempt to save his family inadvertently alters the future, he becomes trapped in a reality in which General Zod has returned, threatening annihilation. With no other superheroes to turn to, the Flash looks to coax a very different Batman out of retirement and rescue an imprisoned Kryptonian -- albeit not the one he's looking for.
