The first one is intriguing in its simplicity, though it might benefit from cropping a bit off the bottom. The second I enjoy very much and am curious about how it might have looked with the camera a bit further back from its original position* so as to capture more of the scene including the reflection. (*Unless it was achieved with a zoom or it was not possible to move further back which is often the case in nature.) The reflection serves to reinforce the geometry of the composition in the third (even if it is just a section of the second picture).
All three seem a little underexposed or dark but I'll say wherever you took the second/third looks like a gold mine.
You guys misunderstood DSience.
This entire thread has been posted twice in two different galleries. There is no need to create multiple threads that are exactly the same.....just clogs up the forums.
After a quick glance...this isn't the first time the OP did this. "Still wet behind the ears" was posted in two seperate places as well. Imagine if all of us did this....the forums would be crazy clogged up.
Now on to the pics.....As everybody else has pointed out....they are way too dark. The other problem is that they are already grainy and since you shot at ISO 1600 and it's underexposed, you will probably have more grain than is acceptable by the time you brighten it up. Composition is okay on the first and pretty bland on the last two (same shot really).
