In the second image, what's your light setting? It doesn't look quite right to me. Is it an outdoor, 360 setting? Maybe it's my monitor but lower the contrast and saturation a bit.
Your lighting in the first AIATHAS (Aiko In A Temple Holding A Sword... ;D..) image looks just right. The trick in DS or even Poser is to get the lighting and shadows right. The shadows adds realism. Take your earlier sci-fi cities... the shadows gave it life and a character of its own.
Thanks dv8_fx, used the new genersis 3 figure, mess up the lighting, I used the dreamlight ldpr render for it , then used one of the actions in that render, I agree it is not right at all, Chuck it away and did another one, i used plane primitives with emissive shaders.
This image is only a test render at low quality, currently rendering this image at high quality, up to now 1 hrs rendering done and looks like another 1 hrs to go.
