Hard to judge how it worked out from those since I have no idea what you actually wanted to shoot.
The technique for shooting blind is very easy and only takes a little bit of practice. For most people. On a film or FF body, put a 35mm lens. Its wider angle of view allows for leeway in the approximate framing of the shot while giving very little distortion. 2/ pick an aperture to give you a fairly deep DOF. 3/ choose the distance to shoot at and set your focus for that. You're done.
Just remember to shoot things/people who are at you pre-chosen distance.
