Do I need retouching my photo?

[Marko]

Welcome photo trims!

Since you are looking for critique - here goes.
These are casual photos that do not need retouching, they needed better planning at the outset .
There isn't much of a connection/engagement here - Both pictures show the participants with no interesting facial expressions and in the group shot one of the people isn't even looking at the camera.
In terms of where these subjects are positioned, that too could be much improved.

I agree with Marko--these read as snapshots, particularly the second. We don't generally do retouching on snapshots. I'd recommend focusing on better setting up your shots (posing, choosing a background, lighting ).
