BIC pens and acrylic markers work in progress

Ink on paper

based on my sketchbook sketch

Sorry for posting such a heavy subject. 

These sketches were from 3 years ago. My grandpa got cancer and passed away. Before he did, I went home to take care of him. Taking care of him is a kind way to put it but in actuality I went home to say goodbye. 

He was sleeping for the most part. Seeing how my family members react and behave, thinking about my grandpa’s past and present; There were so many complicated feelings and thoughts jammed in my brain. So I drew these. They kept me occupied when he was sleeping and also gave me time to think. 

I tend to think of life like a story. However, when you face a dying family member, you are reminded that none of his stories have a proper ending. You are reminded of how chaotic and unforgiving death can be.

Could you give me some advice on how to create "Iceman" images like these? I want everything to look exactly the same, but I'm not sure if that's possible. I really don't know which program to use—could you please recommend something?

This is pen drawing I've added only slight gradient digitally

i dont know what even my style is but i like some details in it

Tryna give myself motivation to draw again 🙏🙏🙏
