Hi Nicholas
Like the first picture, it is close to being really good, the background just doesn't have quite enough seperation.
My main comment s are that all of the images have the subject smack bang in the middle of the image, more thought with composition would help the images stand out. Also given the colourful subjects, In particular the creature carrying the pink bag I would have really expected some pop ... nothing realy jumps out and grabs the attention.
If yu could do something with the background on the first image yu could make a great picture .. I love all the things going on at the same time with this guy, especially the smoke ... some PP might just swing this one.
So good subjects, try some crops and shoot with different angles .... composition is easy to say but not as easy to think about in situ ... sometimes less is more.
