Improving as You Transition to the Middlegame #1

Here's a position from a recent game. Black to move and make progress.

I decided on pushing the pawn to c5. My goal was to open c6 for my Knight with a further hope to relocate the Knight to d5. I was hoping for a Knight trade to fix my pawn structure.

Here's the position a few moves later, mission accomplished.

 White obliged and has nothing going for them as they continue to lose space. 

The coming Knight trade will put my pawn on d5. Eventually, I'll castle queenside and break through on the g and f-files. 

The full game is below.
