2 Games played at a chess night, won one lost one. Tips for a beginner?

Second game, move 13, you castled and lost your bishop. Instead Qd3+ Kg1 Qb5 saves the bishop with the possible expense of the c7 pawn. However it would give you a playable position.

I like your thoughts on positions. But you primarily must focus on 1) safety of your pieces 2) activity of your pieces 3) space/control of board. The structure of pawns and such considerations will follow, but you will improve a lot by simply focusing on those three concepts each game, in each position you are faced with.

Thanks for analyzing the first game as well! And yeah I think I just need to work on protecting my pieces. I watched John Bartholomews chess fundamentals and yeah I think I should start overprotecting and focusing on not making those one move blunders and such. Even though I won in 13 moves I think I need to develop more lol. I have a feeling later on in chess I will start to develop that agressive style but I need to focus on BASICS. And yeah I will definetly start focusing on any possible checks and captures and if the checks themselves are even dangerous. Like yeah why was I scared of Bb4+ when if I just devleoped my bishop and blocked he couldn't retreat down the diagonal and my pawn and knight covers c5 and d4! O_O. 

All in all I reeally appreciate the analyses, I am going to HYPERFOCUS on two things. Possible checks and captures, and protecting pieces with development and such. I have this tendency to try to calculate lots of things I guess and I can get to focused on one thing and totally forget other pieces on the board haha.
