WIP stages of "Zexas Tunnel Action"

Here are the work-in-progress stages of my pixel art piece "Zexas Tunnel Action".

This pixel was inspired by the cover of an old MSX game called Zexas, and the general composition of the image is based into that.

This is the reference image that I used:

And this is the final image that I drawed:

320*256, 60+ colors, made in MS Paint, took about one week.

I drew this in two separate parts; the background layer ( all those blue "speed lines") and the object layer (everything else). And after finishing both layers, I then combined them to form the final image.
