Does practice make perfect? Photography?

I'm getting into photography and I love it so much. I have always been interested in it and I use a Pentax K10D. I'm getting a new camera soon. I'm thinking a Nikon.

However here is my album on Flickr:
(some of the pictures I just fooled around with, but there were some pictures that I thought looked good.)

However I would love to end up taking pictures like these:

Its just beautiful pictures and there's something about them. I would just love to get as good as they do.

So does practice make perfect? Should I try and find a class that does photography (my school doesn't do it anymore)?

Do you have any tips I could improve on?
Thanks!

Added (1). Well actually I never said anything about getting a new camera because I didn't think it took better pictures, I just heard that the Nikon offered more for example videos. I really wished my Pentax did videos but it doesn't.

Stick with the Pentax because it's not about the camera, it's about who's behind the camera. Buying an expensive camera won't make you a better photographer.

You have potental for to make these photos, all you need is some editing software. Maybe a few free online classes (find them on google or youtube) and Take pictures, more and more. Heres a tip [a quote actually] ''Only show the world your best photos, this way they'll think your a great photographer. How do you find your best photos? Find the ones you like, the ones that speak to you. These are your up-most best!'' Hope I helped, I'm also just getting started in photography, and you can add me on tumblr if ya want!
