Nate, do not be dishearted by an unsuccessful attempt. I have had hundreds of botched attempts at various scenes before getting comfortable shooting landscapes. Trust me, there are 50-60 rolls of film that are just me practicing compositional and exposure skills when I first started.
Here is what I have noticed about your shooting style, you like critters and people. Both require good light and controled light as well to look decent. I have seen some of your critter shot and the subject is well defined, color is great and bold and the light is where you want it.
Landscapes are a product of patience and waiting. I won't go Zen on you, but my approach to shooting landacapes is this, where are my eyes leading me? What is the light telling me? What is here that makes this place unique? When I do this, I see (visualization) a world that is different and I wait for when nature tells me it is time. Ask my wife, I have been known to go to a spot and wait for hours just for one shot.
Others have a different approach to shooting but what I do works well for me. If you want to get into some serious read John Shaw's 'Landscape Photography'. I learned a lot from that book and it is a simple read.
With your image here, here are my questions:
What led you to shoot this?
What is your subject?
How does it contribute to the background?
From what I see, there really is not a solid subject here. The background almost stops me from looking further into the image, basically it forms a wall and anything beyond that wall is to be private. Finally, time of day. It looks like this was shot when the sun was directly overhead (Icould be wrong though). Anyway the image is overexposed and there lacks the appeal.
PM me please if you'd want to discuss this more. I am more than willing to help you get through this part of your photographic journey.
God Bless,
David
