Falling Test tube or flying rocket

Sketchbook community, I feel glad to be back to illustrating for this community again.

I made this illustration for a post I was working on for @stemsocial. It took some time but I'm glad to show it to you

I first made a sketch of the ideas I was going to be working on within this work.

---

I uploaded the drawing into Inkscape software and started working on inking it.

---

Inking was particularly difficult because of how disproportionate the drawing was. I was not done in scale or in perspective for that matter.

---

After inking I sated adding color to the test tube.

This is the finished vector illustration
