Welcome, and +1 on asking for constructive critique! First, I love the strawberries in water shot in your portfolio - and pretty much everything in your Personal Projects and Fine Art section.
1. Pic #1 needs a little fill light, but has good contrast and seems to have proper white balance based on the skin tones and white/black jerseys.
Looking at the your sports portfolio, many of the sports shots (both indoor and outdoor) also appear very slightly underexposed (monitor brightness set too high can fool the eyes when editing). But some look great.
2. If you're wanting to improve on your already great portfolio, you need to weed out shots that aren't absolutely the best. For example, I would remove this one since it is visibly blurry and has too many background distractions.http://www.charlesbankephotography.com/Sports/i-LHqfqNS/A
Same for this one. While it does capture a good moment of anticipated action, I would ditch it from your portfolio as there is motion blur and the colors are dingy.http://www.charlesbankephotography.com/Sports/i-gSWDFKg/A
The players in black have some funky gray halo around them!
Just needs to be brightened up!
I had to be really picky to find something wrong, but for some reason the horizontal yard lines aren't parallel with everything else. But it seems you took great care to frame and/or crop everything properly. Again, it's about making it the best of the best it can be.
A very common issue with shooting under stadium lights is with white jerseys. Notice the purple cast on the white shirts and shin guards. When editing, you can dial down the purple saturation (try 40%) and see how that looks. Sometimes blue sat. has to be slightly hit also. And if you have a single, "money" shot that you afford to spend more time editing, you can use the saturation brush to spot-desaturate color from white/grey/black clothing.
Overall, you have done a great job of selecting sports photos that capture emotion and not just action! Also, I can tell you enjoy sports photography, but don't be afraid to capture other moments that are always happening during the games, such as the Marching Band during halftime (I often hide behind props), color guard, drum line, kids playing their own game of football off the field, etc. Really depends on your goal, but it will broaden your exposure to paying parents
The few stray bits of light below the ballerina take focus away from her. I would also suggest a bit more illumination for the face to bring focus off her torso.
Stormy Day: Great colors, but something about the framing and/or lighting just doesn't feel quite right and I'm left wondering where my attention should go.
Hope you stick around! I think you have a lot to offer here on the forum.
