Personal - That’s a nice find.
I have no idea what focus stacking is but the photo looks like to me so there you go.
Effort - I think your power station is more than just a bit of a shoehorn.
Nicely photographed, though. I like the dreamy surreal look and the b&w contrasts. Second photo is really striking.
Technology - Nicely shot, both of them. But I prefer the one with you in it because you look absorbed in playing. You have more shadows on you and your dark t-shirt blends into the background, which I feel gives the photo more drama and mood. Your daughter looks a lot prettier, though, sorry to say.
Horizontal - That’s really nice! A different one on the theme, as you have non-straight horizontal lines.
