Not bad the pose is pretty good but the lighting looks kinda default, I got a few tips u could use to improve your lighting.
1. scale everything to 5 or 10 this give u better quality shadows
2. don't use the sun, idk if u used it here but it's best to turn that off by changing the sunlight colour to pure black and just use spot lights and point lights.
3. tho a bit more of a personal thing, I find that sharp shadows tend to look a lot better then soft shadows, u can change this by turning the shadow blur size down in render settings, anything between 20 and 0 can work depending on the render.
4. a way to make lights brighter is to turn the contrast up to 100 and the brightness up to 50, u will probably have to adjust the spot light and point light brightness so that looking at the render isn't like looking directly into the sun but it's a very useful trick when u get the hang of it
5. you can change the colour of shadows by changing the ambiance colour this is a very useful, tho if the project is set to night you would have to change the night colour
that is everything I can think of for now to help u out hope u find this useful and pls stop being so passive aggressive to everyone.
