ok, first off, lighting is pretty good, and depth is.. obviously great! sharpness is good...and the text, though a little large (as that is your style), is only barely distracting from the focal. anyways, i cant really say much about c4d's and flow because, well, there isnt any. which isnt necessarily a bad thing. it works. the colour splashes are good too.. if i had to make a suggestion, i would say darken up the guy on the left, or make your lighting so that it is more focused on the left
