I agree with Dan, hubby bought you some excellent kit (even though its Canon, not Nikon

)! Some of the photographers here can't afford that quality.
OK, you asked for proper feedback so here goes (if you've been reading posts on this site you'll know not to expect Facebook type Wow! and Awesome! comments). When you take photos to share with other photographers consider the interest level of the photo you are presenting. Mum and dad on holiday somewhere sunny may have interest for your family members but unless there's something special about it other people are just going to yawn, roll their eyes and switch off.
They're nice trees - but not nice enough to sacrifice the photo for. You got good depth of field and good expressions but the harsh light kills all the good points. Even a camera and lens like yours will have GREAT difficulty handling that level of glare. Lightroom is an excellent piece of software but very experience users would have serious difficulty attempting to rescue these shots.
Don't be discouraged, look at the photos others put on here (especially in the beginners' forum), read what the members say about them and learn from the comments other people get. I've been coming here for nearly 3 years and I'd recommend this site as a source of learning about photography over any college course.
I wish you luck and happy times with your new camera. Be warned, photography can be as addictive and as expensive as hard drugs!
P.S. If you change your settings for others to be allowed to edit your photos for the future you'll find that members will be able to show you changes they suggest rather than just try and describe them with words.
