Opinion, not truth.. I also prefer the second one, much more depth, not so over-contrasted, and the colours/shades are better. The splatters look a bit too.. noticable? If you erased some parts on the left, and moved the large splatter on the mid-right behind the C4Ds it would improve it. Can't say I really like the text either, just remove it if I were you. Great job for 15 minutes, though :)
