Left hand A minor pentatonic

Annoying issue that's pretty typical with new guitar players. In the middle of the A minor pentatonic box. The 1 and 3 fingers are down on the D string. The 2 and 4 fingers are curled up under themselves. Working on getting them straightened out. I know I need to keep my thumb lower and that'll help some...it's just uncomfortable to me at this point.

And the game goes on.
