When Ahsoka is first seen walking the along the street, she passes the same Rodian, Quarren, Siniteen and Weequay aliens several times. In the case of the Weequay, he is seen walking behind her in one shot, and then standing on the corner in front of her in the next.
When persons are shown in a still picture on a view-screen in this series, they are usually rendered as a 2D illustration such as when the suspect Jackar Bowmani was shown in the first installment of this arc. However, Ahsoka's warrant is rendered as her usual 3D model.
Ahsoka has to fight clones and police officers while she's on the run. To illustrate the fight, we see her shadow on a wall with the shadow of her lightsaber. The blade of the lightsaber is composed of a form of light, not matter. It wouldn't project a shadow on any surfaces. It is similar to the principle that the fire has no shadow on a lit match.
