Hi Mykhael[ - welcome to the forum from me as well. I think there are probably two streams to thinking about how you can improve your photogrpahs, how you use the camera itself, and then how you process the pictures from your camera. Both are big subjects
. I'll stick with the first stream. Overall I think that all of the shots look like they are not quite focused perfectly.
I like the second and third of your shots best. I really like the second shot of the pick-up, nice lighting and angle of the shot. It would perhaps be better if the truck was less central. The third shot has a nice natrual pose, but it is perhaps distracting with the cut-off legs of the other players in the back ground.
Looking forward to seeing more of your shots.
Nex 5, Nex 6 (IR), A7M2, A99 and a bunch of lenses.
