leaning girl.

I don't see any clues. Best wishes!

Thankyou so much for taking a look, its really appreciated. Best wishes to you both!

Slight girl lean

Thankyou :)

Bit tricky. I can see some lines but not sure what is what? Leaning girl though as I don't see anything sticking up.

Maybe a girl?

Thanks all for your input, really appreciate you taking time out to look for me :)

Slight pink lean but it's not a great nub shot so there is plenty of room for error.
