This is exactly why people need to strongly consider investing in Photoshop (even just Elements) or some other post-processing program. Even small adjustments can greatly improve nearly every picture you take. The problems with your other pictures could be greatly diminished by a little Photoshop action (so don't give up!).I echo what others say about the sunset being your strongest photo. The lions would be great if you had used a flash. That would bring out the color and even up that lighting a bit. I do find the elephants to be decent but not quite sharp and it doesn't quite pop. I messed with it a bit doing selective saturation of the midtones and shadows. I also don't think you should discount black and white when color is absent. If you're offended by me messing with them and posting them please let me know and I'll remove the post asap.
