Hi and welcome to the Critique Gallery.
I see that this is your first upload here although you have been on the site for a couple of weeks now. I hope you will enjoy it and find it a good place to learn. We try to give advice that will help people to improve their photography – both the taking and the editing of images.
Remember that the more information you give us as regards your photographic aims and intentions, the better. It also helps us if you respond to critique and indicate which ideas you find helpful. That means we can tailor advice according to your needs. As you are yet to explore the world of processing I will keep my critique in the main to your image although I would add some small and simple adjustments in processing.
You have a nicely exposed and interesting image here. Great colour and a fun shot too. If anything I would have liked to see the boy's mouth as it blew those bubbles and it is an option at the time of shooting to have moved slightly round or wait for the hand to come lower. Remember now you have made the big expense of buying the camera, the cost of digital becomes almost negligent other than time to sort and process your images. So the more you shoot and explore angles and exposure the cheaper the cost per photo becomes! As well as you can learn and develop your camera craft and eye without the cost of film and processing.
I like the boy in the background looking on at what is going on here and good control of exposure combination to have selected a wide aperture to soften the background. Retaining enough detail in the second boy to add interest to the scene.
The sharpness on the main subject however needs care. At such a wide aperture you have little latitude and the focus point needs to really be on the boys eyes in this type of portrait. The focus point here is on the hand.
Overall a good and interesting image and if that hand wasn't so dominant in obscuring the blowing of the bubbles it would be a real winner.
In terms of processing I would just go for a slightly tighter crop and I'll demonstrate with a modification. I would also introduce a little lens vignette to darken the edges and finish the image as this helps frame the action.
To see the mod, click on the modifications(1) tab between the bottom of your image above and your description box. This will open up a thumbnail of the mod. Click this to open larger and a more suitable viewing size. You can click view large from here if you want to see the full size image in a new window.
I hope that helps and please let me know if the feedback is helpful so the team can try and help you in the best way we can.
Enjoy your new camera and I hope you'll continue to keep posting.
