I sculpted an old man in zbrush, what to you think

Hello everyone, this is my third post here, I wanted to show you the sculpt of an old man I did for a freelance project, i would really appreciate if you would criticise it and tell me what you think. I started learning sculpting in 2018 and I'm pretty happy with my rate of improvement, anyways, I feel like steemit is a wasteland where noone really care about what people post, the comment section of all the post I've seen are empty even if they show some great stuff, it feels like if you need to fing a group of ppl, community, in the website to really communicate, feel like if everyone are bots. Just wanted to say that since it's really hard to keep coming back here
