Hello Ivo,
Welcome to LuLa. Please stay.
User Critiques is for any kind of photograph, not just the rocks 'n trees 'n clouds kind. Portraiture is, in my opinion, way more interesting and way harder to pull off.
I love the second one. A mugshot straight to camera is a bold choice and difficult to do well, but you have nailed it with the selective focus and toning, and the choice of subject. I could look at that one for hours. The first one not so much, maybe it looks better in print than on screen.
I'm curious: why do you work in analogue?
