i dont like either of them.the second one,dont ever lower the opacity of the render/stock when its your focal point.first one lower some contrast.the text could be better in both and have better placement.keep working on them and youll get beter.
Your proportions look off, kinda stretched and messed up. And the c4d looks off, try not to use that as your sole background. Try to blend more, and add some light with a soft white brush. Find a tut, it helps alot, just keep working you'll find it.
