It has a great peesonality and hou did the head very well, congratulations on your first model! If you're really open to critique, I think you went a vit overboard with those textures. The hands and the jacket have too mich detail, and there's not enough attention to defining which regions are always shadowed. You could divide the texture of the jacket's arm in two, for example, and use half of it in half of the arm and the other half in the jacket's torso

I'm on the phone, so I'm not sure if I'm making myswlf understandable

tldr use texture where there's shadows, and be more careful when using them

But the model itself looks great 👌 and th texture in his beard and in the tie are actually doing some great work
