I think this is one of my best portrait photos. Tell me what I could fix
What i did for post process is brighten up the eyes, increased the shadows and color..
Crop is too tight on both sides don't cut arm off
The edgy look of shadows is what sets this apart
Remember that in portrait photography the eyes are what draw the viewer in so I would have added a bit more light into the right eye
The background needs to be more grungy and you'd have something
That said keep shooting your on the right track
