My second i did the same setup but facing the subject away from the natural light.

Settings as follow.

Aperture - F5.6

Shutter speed - 1/10 seconds.

Iso - 400

I also made use of a +1 close up filter as well as a piece of wite paper reflecting light on the subject.

No cropping on both the uploads.

Just resizes both the allowed sizes for the challenge.

God Bless.
