if you're interested in painting in a photo realistic style, tim eitel, one of the leipzig painters, might be someone to look at. he also works with slick reflective surfaces - maybe not so much in his recent, gloomy paintings. here and here. his painting style looks purposeful and fits in with his cool, impersonal aesthetics. so yeah, painting in a certain style is fine as long as you make it look intentional.
it feels fairly obvious that you're painting from a photograph; and while using a photograph as a source isn't bad, you're not doing anything terribly interesting with paint itself either. there's also very little dialogue about space and composition. you kind of slam your figure in the foreground and then there's not much else to the painting. you seem to genuinely enjoy painting, but think of what interests you, what your aesthetics are, how to communicate your ideas in perhaps a less obvious way.
sorry if that's harsh
