Haha that perm/fedora combo is tight bruh I can dig it. Very insightful lol. But word we should do more constructive criticism here instead of saying "nice tones" or "good colors". Like saying one or two things you like, and one or two things you don't like will definitely help us become better in the long run.
But now I get you @reiyjs, I just didn't know what you were trying to do, but now that you explained it everything seems more cohesive. Maybe adding a little caption about what your series is about will help your audience understand what's going on? And I still don't know why your titles are significant (even after googling them lol), so a simple explanation wouldn't hurt.
For me its more about what the viewer takes from the series and what concept they get from it. I want them to have their own ideas about what ties all the images together. For me, if I have a description I feel that it takes away from the experience. But yes, I see what you're saying about the titles. I changed the concrete series to english but for the sky series I'l have to keep it in french, it just flows so much better. This is really good criticism, thank you.
Edit: Scratch everything that I just said. I just finished writing a statement for this series because I'm sending it off to a few magazines that require it. Holy shit. After writing that statement I feel so much better about this series and I feel the images actually work with the concept I wrote down.
