Practice Practice Practice

Practice makes perfect!! I hope that would be the case for my editing skill. I've been playing with Photoshop Cs3 and I'm liking it. There are still a lot of buttons that I don't know how to use though. I watched a lot of tutorials in Youtube but it's still not enough. What can I do? Just practice practice practice!

These are my sample pictures:

Aside from editing, I think I also need to practice taking pictures. I mean, yeah, taking a picture is easy but getting the correct angle, shutter speed, lighting and other stuff is also important. I want to learn a lot of skills in my lifetime! So, if anyone knows a tutorial video that's easy to understand about Photoshop please share. thanks!
