Hey, this looks cool for your first scene.
I am only a noob, but this is what stood out:
Taller bannister (hand rails) - unless hobbits live here
less symmetry (box lids), and less clutter so it feels believable.
Blowing curtains on an unobscured window
And the light seems to be a smeared paint brush on the back window? and the tablecloth drapes don't match the angles of the table... but looks cool!
Lungs not guns....
