Great lighting and not bad for first renderers.
Next is to add some real world physics
The bed looks stone hard
Create an D Former on the bed
select D former field and scale it down and place it where her legs are
use the D former tool (Y axis) to deform the bed so it looks softer
for the second pic you need two D formers one for each knee.
for smaller parts that needs to deform Mesh Grabber also works great.
Mesh grabber also works great for cloths and hairs.
