fairly new photographer here needing some critiques

#1, came out well. Posted resolution too low to really see what is there, but I like what I'm seeing.

#2, is a killer shot; the shapes, colors and dark areas in this composition work for me.
Exposure looks spot on.
Worth shooting that one again trying different heights, distances. Not sure that will yield a better image but it's worth playing with some more.

#3, looks like it is suffering from barrel distortion. It's a sort of weak subject to begin with.

The first one has no mid-tones. The window is too bright and the rest is too dark.

The second one has good highlights but the rest is way too dark. Again no mid-tones

The third one is decent but the window has a lot of ghosting/haze. A lens with a better coating will help with this. overall still a little dark.

Are you shooting in jpeg, or RAW?

Love the composition of your images! One thing I would keep in mind while shooting is the overall exposure of your images. The second photo, while it still maintains detail in the glass panels, is very dark and grainy. Since you are shooting indoors I would recommend a tripod with a lower ISO, situation permitting.

What doesn't work for me in #1 is the disappearing lines moving out of the frame from the top.

2 has some similar issues. I think this would be better if the lines were more square, and the whole thing was framed by darkness. Also, NoFX sucks.

3 is just a shot of a room, and I think it did the job well enough without having much more to say.
