Thanks for comments, Oskar! However, let me disagree
with your "clouds or smth" suggestion. The thing is,
initially, I put in some darkish clouds blended from
the left, but it forced me to decrease transparency
level for the face, so it lost the airy impression I've
tried to make. Finally, I decided on adding some ripples
to the top edge and some texture to the face.

Anyway, I owe many thanks to my neighbours for the great
tiles ;-) Check this out: (1) the eyes (call the girl Lucy,
as I already threw in some diamonds for her in this quilt)
are accidentially locked on the rowing guy by shiftycapone;
(2) the cloud on Aldous' tile below her face adds exacly
what you wanted w/o ruining the picture; (3) RawBone made
a great finish to Lucy's eyebrow and forehead. And, in
overlook, the trio of rowing guy, Lucy and the bee-rider
is very, er, appealing =8-)
