Rendering/technically they are superb Branko. The teller in the first image stands out to me, maybe it is just the posture, not certain. Here in the states they have 'Life Style' imagery on posters etc. showing off a new home or car, hoping to lure you into a loan, in years past they had paintings, but the life style campaign is typical now. Where this is leading is that the renderings are top knotch, lighting great, materials are great, just seems a little empty like there should be more in the scene.
With that said, I understand if the client only wanted to show the space and not impose any design elements. Your last two post of work have jumped up a level in my opinion, looks like you are truly a force to be reckoned with!
