Oh, Zero, I totally missed giving you a reaction on that last one. Sorry about that!
There's a lot of good stuff going on in it, really. The perspective is nice and clear. The details are well rendered, too. The posing and composition are a bit stiff, that's correct. Since you've placed the two main characters at the same height on the image, you did not take advantage of the power of "diagonals", so to say. Everything then appears to be horizontal and straight. In perspective you have the chance to create some strong diagonals, even if these two characters had the same physical height, their placement in depth could allow you to lift one character on the image just by having him closer than the other, for example. It creates a much more dynamic tension then.
However, I also dig the ocean and sky, statue, forest and sense of lighting. Great job on that for sure. Last, but not least, the characters are very clear and we know instantly what we're looking at. That's not as trivial as one might think at this level of rendered details. So...really great job altogether!
