I really like this, it makes me think of the film 'Mad Max', when he's walking down an outback road with his dog!! I do have a couple of criticisms though, helpful ones though!! Erm, the dog just seems to be a bit too big, and the shadows could be slightly altered!! Using another layer, try putting a gradient in place of the shadows, that is darker nearer to the man/dog, and more transparent and blurred the further away it gets!! Hope I've helped ya', and not annoyed ya'!!
Thanks for the reviews,I will improve more and is great to count on your help.... XD Mad Max... I love this movie, I will work in a project on the same line post apocalyptic...I think you'll like! Soon.....XD
