C&C for only the 1st :
too much going on in there .. (c4d's & stuff)
The bg isn't clear much ... Ruining the concept ...
Text could make it a little more attractive
Other than that it's good .
Off topic:
Ur current one looks really interesting though ..
^_-
well i think first one lacks blending and agree toruk with other critiques
at the second one u chosed wrong colours because it doesnt fits with render.. aand it lacks blending too (it's only my opinion though)
