Office work

Tried using lighting this time.

And one without the lens flare.

I think without lens flare is better. The light isn’t bright enough to warrant one like the sun would be.

Lighting is simple but otherwise alright.

That’s lighting? Can’t see any lights or lamps.

Was looking at the faint shadows below the mouse and keyboard, but then again, those could very well be the default shadows.

In that case, you need some spotlights to cast more light into the scene. Ideally placed at a source of light and angled towards the subject. To make it invisible, use the colour tool and just set the alpha to 0.
