Good job on getting out there and getting this shots, I'd suggest taking the next step and refining these images in adobe lightroom/ACR or something else along those lines.
Also can you give us feedback on your thoughts and opinions on your camera?
Yes Adobe can be a next step, but I don't have CS6 anymore, nor do I like edited images. I'll might look for alternative free software for the next topic.
Sure Purple. I think you want to ask if I like my Nikon D90. Sure the body D90 is great and it was the world's first DSLR camera with a movie mode (720p HDTV quality) and HDMI output. Though, I would not recommend the body for making any videos anymore. There are better Nikon bodies in the market right now for filming. I would recommend the D90 for non-professional photographers. When I brought my camera in 2009 it was the best Nikon body for non-professional photographers. I have a 35mm Nikkor lens 1.8 which is one of the best indoor lenses. Also have a cheapass Nikkor 18-55. Need to get 600 euro to buy a 70-200 for outdoor shots, but all in all I'm content with my gear right now.
I must admit that I haven't checked the latest models in years. When you get better at photography you quit with caring about the latest stuff. What matters are the composition, the light and the focus. I'm a fan of Ken Rockwell.
