Need help to see what I did wrong in these 2 pictures

[goodguy]

Been to the mall today with my princess daughter and I took some nice pictures but these two just didnt came out as nice as the others.
They are not sharp and to me they look slightly out of fucus and I was wondering if you can help me to find out what I did wrong.

I used apature F5, 800 ISO and 1/50 shutter speed and focused at the end of the coridor.

Maybe I should have focused at something closer ?
Maybe I should have used a higher apature number ?
Maybe use a faster shutter speed because maybe the picture isnt sharp because of the relatively lower shutter speed I used on the picture ?

One important piece if missing information is the focal length used (the EXIF data has been stripped off these). My guess is that they are slightly soft because of the low shutter speed. Looking at them carefully it appears that the foreground, especially in #1 is in relatively sharp focus so perhaps your camera wasn't focusing where you wanted it to.

The focal length also would affect the optimum shutter speed. If you focus manually, you get maximum coverage focusing about 1/3 of the way into a scene - there is more DOF behind the plane of focus than in front.

Focal length was 18
