Where does this come from?

Hi all,

I found this motivational poster with some Crimson Skies -like planes on it, but it is something else..


Does anyone know if this is just a single artwork or that it comes from some game or anything? It looks cool!

Greets,

It's a guy on deviantart called ukitakumuki. He's also been featured on conceptships I think.
