Illustration work/ past ideas

Here is a few of my rough first ideas, at the top I was playing with the idea that the street children are often ignored and so blend into the background, I do actually like these but it's been done before so I decided to leave this idea. 

The last few, I was playing with the idea of seeing the street children and very literally putting them in an eye shape, really don't like these it's just too typical and easy, I think.
