Kelvin grove gallery painting ID

Hello, wasn't really sure where the best place to ask was but thank you for anyone who can help!

I saw a painting whilst visiting the Kelvin Grove gallery earlier this year and I've forgotten the name or artist and would really love to find it again.

It was a large work of a man looking out of a window or door, fairly modern and quite large maybe around 8 square feet or so? It was on a stairwell near a window.
