Looking at just these two games, it looks like you were making mistakes in these kind of category :
*) Making too easily space for pieces from your opponent to try to defend, by opening lines for them "for free".
*) Not calculating some checks thorougly (16.Ng7+ wins the knight on f7. That was not too difficult to spot).
*) Trading too many pieces while trying to maintain the initiative.
*) Maybe resigning too soon.
Looking at the last point, you can also ask yourself this question :
When I don't see a winning move sequence when attacking, or when the opponent makes a defensive move that you overlooked, does that interfere with my "objective" chess position evaluation at that very moment, and/or does it disturb my "winning mood" so that I cannot think that clearly anymore ?
If that is the case, see if - next time - you can do better, and overcome that slight psychological setback by recognizing it, and don't give up looking for a better move even when you feel like you have a lost position or lost the initiative or attack.
In the past several chess players, including chess masters, have resigned chess positions because they thought they had a lost position, which was not the case.
The moment our mind is in "resiging mode" it becomes more difficult to find winning or drawing moves.
Here's one "famous" example.
Marco resigned here as black, overlooking the fantastic save 36...Bg1!! and his opponent can resign instead.
