Headwings = upper 'horizontal' stroke Arms = lower 'horizontal' stroke (curving downwards somewhat) Partially-open peplos dress 'split' into two sides by legs = downward left and right strokes.
(Less apparent in the Great Sky Goddess version, though there the hair also form part of the lower 'horizontal' stroke)
She kinda sort of has the 天 silhouette before with her arms open, but now it looks more apparent because of the open peplos dress (it was closed in previous depictions of her), so I think this is intentional.
Though Zeorymer itself also has a similar silhouette sometimes when punching both hands together with feet apart. With the pauldron spikes forming the upper horizontal stroke.
