Hi Adel,
I'm glad to see more of your pictures. The first one (tree silhouettes) is cool. I wonder if you could have made it more exciting by allowing the sky more exposure to give a deeper color.
The flame is beautiful, but would have more meaning if there was a context. What is creating the flame, what else is around it. Adding one solid element to the picture would move this up to the next level.
The teapot in the ashes is great. The vehicle in the background adds to the story. The only thing I'd change would be to move your flash off your camera so that you don't get the bright reflective glares on the pots.
The one of the bird rubbing his beak against his foot is striking. What an incredible bird! The ordinary objects in the background, however, detract from an otherwise regal image. (The blurred background helps, but it's not enough.)
The one of the four camels in the sunset is my favorite. Could you have left the open space on the left of the image (rather than behind them on the right?) Unless trying to create tension or unbalance, it's usually best to leave open space in the direction that a subject is looking or moving to give a sense that the subject has somewhere to go.
Looking at the photo of the bird standing on the glove makes me wonder if you have a relationship with that bird that would allow you to get up REALLY close with a camera. If so, you would be able to take some detailed pictures that someone like me may never have a chance to take.
