Pen drawing (Spiderman)

What's up beautiful people,how are you all doing,it's another episode of my pen drawings,so I checked my gallery and I saw this artwork I did some years back but still looks refreshing to me,Spiderman has been one of my favorite superhuman or sci-fi movies as well as some of us,how did it start?
I made a sketch with black pen to create a skeletal form,don't mind me in the first picture,I look so young😆....I made sure the lines were a bit thick cos they were confusing especially at the neck.
It was all shaded with red and a little of black to tone some parts down,a shadow effect,visible in the neck to project the head,the vertical/horizontal lines were made to bend and curve to show perspective and body forms in the suit .
I created a light sky to as not to have a background conflicting with the real drawing,the contrast has to be balanced,also I added some buildings cos what more could fit in for a spider Man who jumps from a skyscraper to another,i believe a perfect picture zoomer will observe the City view reflecting in his eyes.
This is a work done on cardboard with majorly red pen,black pen,yellow and blue.
Here are my progress shots:-
