Love the first one, the clipping masks/clone stamps to the right of the render look odd though kinda pixely in places, but still looks good. very nice lighting/colours. any chance I could get that render? as for the second one, smudging is kinda basic and if just looks like an effect c4d throwen over a render. good flow/blending/colours though.
Sweet tags. Like the first one best. Nice lighting, depth, and fx (though maybe the first one has a little too many ) I like the flow too.
Nice and smooth sigs you got there. I particularly like #2. The lighting gives superb focal to it, though I'm kinda 50-50 on the clipping masks.
