First image is has a green cast on the wood to me, or were they really green? Your horizon is straight from what I can tell, so that is good. The image does nothing for ME personally, just kind of boring. What were you going for here? Why do you like it?
In the second image your subject is dead center, study composition ( I still am ). Your DOF looks good, but to ME the subject looks a little out of focus. Could just be me though. Again with this image, kind of boring to me. But, that's ME. Still ask yourself what YOU like about it and why you find it interesting. Maybe another angle or perspective would make it a little more interesting.
Again, these are my opinions, and I'm a noob too. You could really take what I say with a grain of salt!
