The glass is really quite elegant in its simplicity.
For the photography, I would like to see two types of photographs:
1- There can be one overall photograph, which shows the glass in its context, at least the entire doorway. I would use the HDR (high dynamic range) imaging technique, where one shoots two photographs of the entire doorway, using a tripod. One photograph is exposed for the background through the glass, and the other is exposed for the actual door and surround. The glass looks quite good in your top photograph, so that type of exposure looks good for the glass, but the door is too dark. In the second photograph, the glass would be burned out but the doorway would look good. Using photo editing software, the two photographs are merged. If this is done well, it can help to mimic the dynamic range of the human eye without appearing unnatural.

2- There can be a number of closeup details of the glass in varying light.
