new camera macro shots--what do you think?

[PL-Reef]

Okay so this is my first 'real' camera, I got it yesterday and am experimenting. Here are some macro photos I took, let me know what you think and any advice would be appreciated. I know the glass is dirty in the tank, (it's my boyfriends tank, not mine) so please ignore the dirt. Thanks!
