I dont want to be mean, but you asked for cnc so: Text does suck, Looks a bit monotone, The white wireframe thing you have going on is kind of bleh, No depth, Focal is kind of off, No real flow or texture to the bg. Work on those things.
hmm it looks kinda cool how you said text def sucks i think you could have done something more for blending the render. i mean the right side of the render. nice job though
not bad, but this one actually could use a little depth, such as behind the focal i kinda like what you did, but its a little lackinig and I dont see any reason to say something about the text considering you already know
