Welcome to UHH Brooke, it's a fun site. A dog and a kid as subjects, you can't go wrong.
One quick suggestion, align your images horizontally. post process, or when composing.
Welcome to the forum.
Don't worry about being shy. Most of the people here are great.
As with any group, there will be very opinionated people- just let it roll off your back.

Welcome to UHH Brooke, glad you joined us. I am close to you, Ellenton, Florida. Good first posts. If you would like some in depth critique you can post in the "Critique" section ( tough bunch there) or in "For Your Consideration" (this group a little more forgiving). The forum is made up of many sections, street, people, sports, photo gallery, etc. Click on "Home" at the top of the page, then "All Sections", then subscribe to the ones that interest you.
Have fun, learn and enjoy the forum.
PAR4DCR said it well. Go to the top of the page. Click on home. You may have to scroll down to find "all sections". But yes, For Your Consideration and the section on Critique may get you what you are looking for.
I also like the train shot. It looks like a good candidate for a B&W conversation.
Welcome to the forum Brooke.
Thank you everyone for the warm welcome :)
