My first post. SX40 pictures

Hello everyone, I am new to this forum and new to the SX40 as well. I am a major amateur, and am just starting to learn about ISO and all the other camera lingo and what it all means.

I just thought I would share a couple recent pictures and see if anyone had any advice for me or what I could have done different? I am still finding that my shots are a bit on the fuzzy side, but I'm not sure what setting it is I need to change. And I keep forgetting to keep my darn fingers from being in front of that sensor on the front!
