The balance of the photos is excellent, almost perfect. The bottom right is something that could perhaps be punched up with curves and or levels, it's slightly distracting. The bridge and the sky are excellent, I find sometimes after taking a shot that it would be nice to take another crack at the framing as cropping doesn't always allow what you would like. A very confidant and well executed photo overall though, Good job!
I would recommend the 50mm 1.8 prime as perhaps the next lens to purchase for your kit, You will get tremendous sharpness out of it and it would be ideal for stuff like portaits or fixed objects etc. It is about $100 and far sharper than the kit lens. On the cheap one of the best and most rewarding lenses to buy. ("jay" was taken with this lens if you check my profile)
This is so mesmerizing for some reason! I really like it! Maybe because of the whole, "rule of thirds". Don't know if you realized you did that...but, that's probably why this whole composition is so perfect! Very well done!
Successfully shooting into the sun ... very nice. Not sure how comforting I think it ios but I am not judging too much on that fact for this challenge. In other words you could have built this bridge , supplying your family with millions of dollars :) ... that yould be comforting!
