Relatively new to MTG and this is my first constructed deck using whatever cards I found in boosters. Any advice would be greatly appreciated!

Two things,

It's noticeable that you have lots of one or two ofs. It's better to get rid of those and play more of the cards that really work. I understand that you probably only have one or two of a lot of the cards you're using, but once you get multiples it'll make the deck more consistent.

{Ride Down} is the bomb. If you're playing against decks with creatures you'll want four of them.
