I'm gonna take the time to go through your gallery. Only recently re-realized how much I enjoy these.
Captivated by the translucent eyes of the first one, but opaque eyes works well here; especially with them feeling a bit further away.
With Dash being the furthest back, AJ feels more involved in the group. Also true with AJ seeming more energized and facing the side rather than the back; and Dash's adorable presence is still clear from the air. As a squad, they feel more united. And as a picture, it feels more complete.
On an individual level, the close-up detail in "Cheer!" really breathed life into Rares and RD. Everything about them jumped out at me. Here, all three feel involved, and have great poses (AJ with one hoof down, Rares reaching out, and RD rising high).
They feel quite different from each other, but love of 'em both. Great work.
Ouuu! And RD's headband brings out a new type of charm :3
