Overall, these are good shots. You caught the little guy staring right at you with a great smile and the curiosity shot is great too. For some reason my wife really likes shots taken from this vantage point, but I digress. With the B&W shot, adjust the RGB along with the contrast. This will sharpen the details more than the "auto sharpen" function. The color one could probably do with a tweak on the contrast as well. Which editing software are you using?
I am having no luck at adjusting the RBG/Contrast in the B/W photo. It either turns out too bright, or too dark. Ive always used the " convert to black and white" option, but now that I have seen those type of B/W shots, that really POP...Im jealous! EErrr!
Constructive Criticism please. How can I make these better?
Don't dress the lil guy in clam diggers.
In addition to what's already been said, if this was a crop, back off a little bit and give him some more room on the sides. I really like the vertical orientation, that works well with the slide. Maybe pan upwards just a bit to get rid of the dark shadow under the slide.
