Hi Marieke,
Nice, I like the atmosphere of your shots!
Door: Good idea, now why haven't I thought of this one before? I like this one very much. Personally (but I'm a straightness freak), I'd change the perspective a bit so the door is straight again.
Below the coke oven: Classic shot. You managed to keep the highlights in the windows very well, this means you took the right amount of brackets. Excellent! If I have to comment, I'd say I would make it a bit “darker”, that would do the atmosphere of the place even more justice, I think. But other than that, nice shot!
Looking out for more
Thanks for posting!
