■ I like the first one a lot. I think the colors of the render flow well with the b/w background, but I feel like its a bit to dark. I like the text on this one. ■ I dont care for the second one, its kind of boring. Looks like a pic of some buildings for a bg with a c4d slapped on there and a render of some guy. Not very appealing. ■ Im kind of iffy on the third one. I dont like the colors for it, but in the b/w version, I dont like the flow of the bg. Theres something missing in this one methinks. Overall, not bad. Keep up the good work.
