Colors were good in the 3 & 4 shot in the OG post, but what purpose do the shots serve? Whats the meaning/story/importance behind them? What makes them more than just a mom with a camera on the side of a hill? (also applies to shot #1)
Second shot in the OG post - butt shot, not usually appreciated. Lighting is flat, and the stairs/overhang are distracting. Get a few flashes & ebay poppers to help the rider stand out.
Fire shot - underexposed, framing bothers me.. cut the tree shadow out, or do more with it. Dont just leave it in the corner.
Rollerblade shot - Again need better framing, we lose the shot with the most action in it as hes too mixed in with the building. Also kind of lose him on the landing shot. Too much room on the left, looks like an awkward start to the sequence.
Fireworks shot - Probably your best in this thread, wish there was a little bit more of the ambient light (street light?) Also wish that the furthest left light streak (all white) wasn't there, but nothing you could of done to prevent it, photo shopping it out would be unethical. Also your watermark is too big/prominent. On this shot it was the second thing I saw. Creates a nice triangle out of your points of interest ( Firework > watermark > street light) but that's not what you want out of a watermark.
Flame me. Do it.
