DC has posted some concept art done by Andy Kubert. Arthur Curry now has a crewcut...and looks like he means business. Here's what Kubert had to say about his character design:

“What you’re looking at is probably my very first drawing of Aquaman. For Flashpoint, he’s military, tough and rugged with a scar on his face. You can see a lot of Sgt. Rock in his look…but that’s probably in my genes! I gave him the buzzcut to help with his background and decided to keep the trident like the original one…why mess with a good thing? The fins on his boots in this sketch didn’t make the final cut for the series. I like the take no prisoner attitude that he portrays since that’s his character. Someday, I’d love to take a crack at a hard-hitting mini-series with him. There’s so much visual that can be done with underwater techniques.”
