Hey Cassiebsg =)
I think it's anything but crap! You've got some nice weathering to the stones, good overall ligting and it's all ready to just put in some context or a paintover. As for the 3d side of things, i would really recommend trying out Blender. It's completely free and I know several professionals who use it exclusively. It even has texture painting directly onto the model so there's no need to worry about being too prescious when laying out UV's and things. There're plenty of free tutorials on Youtube too that'll get you started.
Hope that's helped and hasn't just been a total "eh? what? Blender who?" kind of thing. Keep going though, please. I'm really anxious to see where you go with it!
