WHAT’S GOOD ABOUT THEM Really like the fact that you used a rig. The poses are pretty good
WHAT COULD BE CHANGED The lighting. I’m guessing you’re using Blender. Try using cycles render, then look for HDRIs. There’s a lot of tutorials on this on the net, from what I remember.
Thank you, I truly appreciate your feedback. Furthermore, when I made these renders I was extremely new to the render engine, so I always used Evee instead of Cyles because Evee was a lot faster in Render time. After a while, I learnt that Cycles reduces shadows and makes your render a ton better.
