|*Hello from Sid and the Critique Club*
A fairly pleasing portrait that meets this open themed challenge.
A portrait of a child at play that in itself will naturally have appeal to most viewers, and it does but there are several things about it that set it apart I assume intentionally but it doesn't work that well for me.
The moment you have captured is one that feels more posed than natural and his expression does not convey the sort of pleasure I would hope to see in this situation, there seems to be a degree of apprehension in his face. He is too central in the frame I would prefer to see him further to the left but I think this side on viewpoint could have been improved upon with a change of position looking up the seesaw towards him with him against a much less distracting background. Talking of which the chosen aperture has given you more DOF than is desirable for this composition.
The thing I have the biggest problem with is the processing, and again I assume you have deliberately chosen to present it in this way but I don't know why. I find it much too contrasty and grainy. I can only assume you have tried to emulate an old box brownie type of snapshot? This would make it a lot more understandable if you have and is starting to make a bit more sense to me now. Together with the other aspects I have commented on it feels as though you intended it be interpreted much more with the snapshot theme in mind, in which case well done.
As you can see that interpretation was initially lost on me and I'm sure, most of the viewers here, but well done for approaching it in this manner, (if you have), Sid
