Nice work Nick   it's either the cloud edges or the closeness of the formation given that they're already rolling into the break.  Perhaps another 10ft (relative to the Raptors') apart and it would look like a realistic formation.  Or a tiny heading change on the rolling birds.  That's just my opinion and as it stands it's a good pic.

nice one1! i agree with mustang turning the two that are breaking a little more toward the outside i think would do it and maybe spreading them out a bit like he said.

great job though!!
