Slippy is in trouble -Star Fox Pixel Art. and music (with tutorial)

hi Comunity, today i made this pixelart by request of one friend of mine, a music artist who love STARFOX. he ask me if I can pixelart slippy floating in space for his song "space frog", I put the music link with his permission.

fox, help meeee!

first try to make the lineart I look for some slippys pictures and some spaces frogs around the web.

you can use the colors of the original image to make your palete. I ever use 3 tones (dark, medium and light).

keep drawing the uniform in one color base.

when you finish with the base colors start with the shadows and light. (using your palete) and add details.

I hope you enjoy this art an tuttorial like me. your up vote can help me a lot to continue this serie. thanks!
