i've done photography exhibitions and had modest success with photography

your sense of composition and balance is very good

that photo is under exposed. make your aperture wider (smaller f number like 2.8) or set your shutterspeed slower to let more light in.

play with this curves tool in your image editor to get better tonality (contrast) as yours is a little flat

try auto color settings and then maybe some kodak portra nc filters for darkroom or vsco. don't overuse them.

edit: also you should largely be composing with shadows in mind.
