lebesgue72 vs. VMogila: A40: Modern Defense

Hi all! This is a recent game I played. If I were to play it again, I'd be careful to calculate the possibility of losing a pawn if I decide to go in for some variation - in this game, it seems like my c4-c5 pawn move was tactically o.k., even though I didn't consider the position's possibilities too deeply. But more importantly, i would change my move 19 to not only attack the knight twice, but to look out for the tactics(since it was mostly a tactical move). Finally, the opening happens to be called the "Modern Defense." I know very little about modern chess, so maybe there's some instructive value to the way that my opponent played it. It seems like the d5 move blocks black's light-squared bishop from seeing the world, but because of the tactics in the position of the game, that wasn't quite true. That's interesting, because I haven't seen too many instances of that happening. I guess I would take that as an extra idea/pattern to be aware of, to store in the bank. Its validity would have to be tested in games that I play in the future. Here's the game:
