I did get the bit about brownies being invisible, and it's a great landscape, but I was divided between rewarding a very creative shoehorn and the fact that is was, well, an obvious shoehorn. I gave it a politically neutral 5.
Normally I wouldn't rate very high because its only a creek...but the way you captured the water like that honestly mystified me when i first saw it. id saturate the greens more to make it pop :)
Now this is a beautiful calendar shot! A top-notch landscape shot that would score really well in a challenge geared to those descriptions. But I just don't see any brownies in the shot at all - they are not visible to the human eye (well, see that was my point the artist might say). I have looked at this several times to make sure that I am not missing any camouflaged creatures but I don't see any unless you made them very, very, very transparent that they effectively disappear. I feel one should avoid relying heavily on the title to carry the idea of brownies being there but not visible to the human eye. I believe in the storytelling adage of "Show, don't tell". The title should complement the shot but not carry it. I have the expectation to see a creature of the mythical sort in this but none has been made visible and there-in lies the problem. I am being very honest here, I just cannot give this shot the full marks it deserves because it does not meet the spirit of the challenge which is mythical creatures. Voting on this one is a tad difficult because while it doesn't truly meet the spirit of the challenge (there is always the chance you have camouflaged them really well - all monitors not being equal in lighting) I can't bring myself to vote it extremely low either.
