Nice subject matter. I generally like the built in frame, but I think it may be too big here. but I like the waterfall and the plants add a little mystery to the waterfall. Also I like the the flat water above the waterfall.
My two minds are 1; Is the composition ok, as I am still trying to learn the basics of it.
2; Oh I don't know, I think it's just the composition side of it. :roll:
I agree with the comments about the border, it is a little too big.
Thanks guys you've given me a bit more to think about, which is a good thing.
I hate to rain on this but the border is waaaay too big and not necessary. The firns as a border around the falls is the right idea and would be all the border this shot needs. I would like to have see more of the waterfall and less of the firns. Also a little overexposed.
Here is a link that shows some basic compisition rules. Check out a bit more at this site as there is more than what I linked to here.
I hope this helps. http://www.betterphoto.com/exploring/tips/thirds.asp
