not a fan of this one. If the nose was sharply in focus, I could understand the bokah, but it's all slightly out of focus and the crop is a bit strange. It's not bad, but I'd keep working at it.
Again, the crop is the same as the last one you linked to: awful. The Koala actually looks like he's trying to get into the frame! Sort your crops out, and you'll actually have some really nice shots. Also, put your photos in the thread!
On Flickr, go to the photo you want to post. Next to the Facebook and Twitter icons above the photo there is a drop down arrow, click that. Then click "Grab the HTML/BBCode", make sure "BBcode" is checked, copy the code and paste it into your post. Voila! The picture is now in your thread.
