Photoshop Attempts

I have decided to Photoshop specific pictures to develop my skills on the application. I will show them and describe what I have changed with a before and after picture.

Before editing: 

This image has a wire in the background which needs to be removed and

the fence also has a bar coming from the back of the childs head which I

would like to remove.

I would like to clear the childs nose as it is not suitable for a magazine

cover and better the colouring on the fence.

After editing:

 I have removed the wire and made the fence more evenly coloured with no seperate parts behind the child. I attempted to change the childs nostrils as they were not clear and I am disappointed at my attempt as in my opinion the right nostril looks extremely round compared the other one, which does not look natural.

Before editing:

This image also has an uneven background which I would like to change and I could slightly change the resness in the childs face.

After editing:

I have sorted out the uneven background quite well, however, by doing this the right ride of the childs face is a little out of focus which is irritating and I am attempting to fix this.

once I have sorted out this blurry area I would like to use this as my magazine cover image.
