Welcome!

i used the tent to make hair strands using liquify, then i used the grassy background for a head, then i used the sky/bush for the eyeball color (using radial blur). i also used the shadowed part of the tent for the eyelid. i also used the sky/bush for her dress under her yellow coat (which i also used the tent for) and for the dress i used radial blur as well and also ocean ripple.

for the sky i enlarged a small section of the sky from the source pic and used a rainbow gradient but very low opacity.

i used the air folds from the bottom of the tent to create roots and the rest of the tree. i used liquify for shaping the branches.

i threw together all different folds of the tent to make some sort of dwelling for my bird lady... but later changed the color to make the image more vivid.
