Oh yes, good ol' Tassie. I lived there for about a year when I was a little fella. Who would have thought that an island so small has no fuel stations for 184kms? But anyway, to your photo; I like it, I like it a lot, but I think it may be just a little too busy for the effect you seem to be trying to achieve.
I love the whispy clouds, they are a beautiful characteristic of that part of the world. I think the one thing that may have made this photo much more successful woule have been to park the car on the other side of the road. This would have allowed for the same basic idea (to go, or not to go) but in addition to that, you would have has a winding black road, getting lost in the distance. Doing this would have made your audience look at the image and then get sucked into its every aspect - and *that* is what photography is all about.
I have looked over your portfolio (your wonderful portfolio), and by no means am i suggesting you did this wrong, I love this photograph, I think it is wonderful, but we are here to critique each other afterall =)
