Ok, first game against Vkraturi - 2 knights is usually a risky opening, and you lost a pawn there so you should play aggressively. 13...c5 is a mistake, at least you should have gone 13...Qxb2 and get back the pawn. 14...Qg6, i know you want to go for g2, with the Queen/light bishop, but I think Castling is better here. 21...g5 is bad too, the position is quite open, and the king shouldn't be exposed. Maybe 21...Nc6 or even Bxd5 is better?
Next -against Kimochess, your opponent gives you a chance to set up a big pawn centre with 2...Nf6. Take advantage of it, play 3. cxd5 Nxd5 4. e4, and you'll have great centre. 5. Qd2 is a blunder, although you followed up with sensible moves.
Against Nante27-75, I think thats an opening called Bogo-Indian. Instead of blocking the check with the knight, maybe Bd2 is better as an effort to trade your bad bishop for his good. Also, generally you don't want doubled pawns. However the decisive mistake came at 15.Qb7. 15. Qb5 is a move you should consider. You are too aggresive there. Just be happy with the extra piece, try to trade and head to endgame. Remember in rapid chess generally, Queen > Rook + Bishop, because of tactics.
your 2nd one against the same opponent, Qb4+ is okay but Qe4 only lets your opponent develop as in the game. 9...Qxb2 should have been played. Your opponent is winning in the middlegame but you could have shown resistance with 23...Qc5. Don't expect your opponent to fall for cheap tricks, lol.
Game against Azust - Your doing well, on move 18 though, maybe you should consider taking on f5 withyour e4 pawn, as your opponent is uncastled so opening e file might be good for you. 20.f3 is a bad move, not only it weakens the king but also it deprives your pieces from defending the king. If Black goes Qg5/Rg6, you could have stopped mate with Bf3/Bg4. I think the problem was your Queen was too inactive from the beginning, after winning the piece. on your 12th move, maybe you should have played 12. b3 or 12. a4 to undermine the big pawn chain your opponent has.
That was real fun digging into analysis. I hope you didn't find my comments offensive. I'm also rated around 1400 in live chess, maybe we should play each other sometime.
Just like all low rated players, I've been dilligently putting lots of time into training tactics. So far I've done 39 hours of tactics training and gotten my tactics ELO to 1600. My live standard rating is ~~~1400 and Im having a hard time progressing past this level. It seems like my opponents are always just slightly a step ahead of me, and I win only when I can take advantage of their obvious mistakes, or when positions are very vague. I've compiled a list of newer games that I wish people would look at and see where I am falling short.

I lose a pawn in the openning and it is my demise as it makes the endgame pressure unbareable.

I do alright tactically, and even win the exchange, but this ends quickly with a positional mistake.

I get pushed around until he wrecks my pawn defense, and I see no other way than to accept his temporary sac. I get greedy trying to find counterplay and blunder away.

I win a piece with tactics, then very quickly get my queen trapped.

I play very aggressively, and I feel as if Im on the verge of a devistating attack, but it gets dismantled slowly with my opponent put in a commanding lead.

Once again I get a piece ahead, then succumb to vague positioning and an opponents strong attack smokes me.
Recently, I've been working on reducing blunders to 0, and I'm getting better, but some mistakes seem to turn into blunders 20 moves later.
If anyone has anything specific to say
