Fidel, I apologize for not following up on the shoot. Hehe, sorry. Next time, tuloy na talaga. Somethin just came up.
I like the composition of #22. You captured it well.
Re the underexposed photos, I recommend adjusting the color curves (which you did already). Noise reduction has the tendency of blurring details a bit, imo. But either way will be fine, I guess.
The best solution however is to buy the F/2.8 VR (Nikon term, so translate to Canon) lens! Haha. Downtown SF has a great camera discount store almost complete with everything since the turn of the century. ;)
