Now the time has come I critique one of your works^^ (in english so others can read it too )
The first impression is really good! everything looks symmetric, the lines meet in the middle of the picture and the focus is pretty good too
The different structures of the wall look awesome too! Above all I like the glossy white because it mirrors the lights and the people!
The lines make the eye move immediately into the center of the picture and give the viewer a oppressive feeling (which is actually good^^). You feel a bit like your are getting absorbed^^
What disrupts me a bit are the colours in the center...the viewer focuses on the purple sign which shouldn't be I think. So maybe you could have made the photo black and white - which will suit the picture very well in my eyes
You can also work a bit with the graduation curves and/or the tonal values
Editing often makes your photos better so don't be afraid
