The first is very nice.Has good flow to it. Second not feelin' it.Coloring seems off and it's over sharpened Third I think could use more to it.Maybe add a couple c4d's to it.Not bad though.
All of your tags need better typography, more flow, depth, bg, and effects. They aren't bad, the compo is good, but they're sort of plain. Do some tutorials, hun. ^_^ You'll improve quickly, I'm sure.
Thats what I thought, too. Try to add some C4D renders if you have some, if not just go into the resource topic. The first one is the best, so far, I like the colors there, pretty nice. The other too are looking a bit strange, not feeling the compo there. Definitively good as some first tags, tutorials and labeled psds are the best way to get better fast.
