Being a newbie, I would like to have some comments on my current skill level and quality of my current equipment. I own a Nikon D7000 with 18-105. I am not very much satisfied with the quality of photos in terms of details and sharpness. Maybe you can have a look at the linked photos and see if this is the best I can achieve with my equipment.
Here are two sample photos (Newly added)
No post processing has been done and both the photos were shot in JPEG Fine.
