We never see the Winter Soldier straight away - he always appears on the scene out of thin air, which makes him seem all that more menacing and scary. Also,

[The Winter Soldier is] never in a hurry—we only see him running once in the entire film. […] Captain America frantically runs […] while the Winter Soldier casually strolls to his destination, stopping only to kick people into jet engines. That contrast is subtle but it makes the Winter Soldier seem more in control—he’s already there while everyone else scrambles to catch up. (x)
