Any tips?
You are brand new. Have you tried the Game Review after a game? I see one was done on your last game but I can't tell if you did it or your opponent.
At any rate, Game Review presents you with the chance to find your bad moves and try to find better ones.

In the above position, your move Qb3 was not the best. It offers you the chance to retry the move. (Your queen had been at b5.)
I think it is very helpful to use the "Retry" button rather than just looking to see the best moves.
Also, everyone wants tips. Lessons are really just tip collections. Try them.
There are tip collections/lessons available for every phase of the game.

Most important is to blunder check before you move.
Stay away from blitz & bullet and play 15|10 rapid.
