The face doesn’t appear to be as focused as the bottom of the shirt and teh jacket, ie you’ve focused in the middle of the picture instead of the face?
His face seems like a wax work too.
What lens and camera did you use and how close to the subject were you?
Yeah the composition is fine alright.
Look forward to seeing some otehr pictures.
Using a 50mm 1.8 might have gave you a better result than the lens you used, you can pick them up fairly cheap online or around 125 euros in shops here.
