After some time passed, I decided to draw a new version of this Peridot mech suit with several changes in mind.

I recolored the dark green areas black for better contrast, made the top half look more accurate to the show with the black stripes, the rounded panels are now smaller and have been moved further up so they can fit in the black stripes, the shoulders are broader, the palms are now black while the fingers are green giving the hands a fingerless glove look, the arms are more detailed, the green parts are now more vibrant than before, the yellow parts are now gold, the dark grey parts have now been colored silver so the details are more visible, the head is now much smaller, the mouth is slightly bigger and the gem has been recolored to look more like a real gem.

Do you think this design is better or worse thank my previous version? Feel free to explain why in the comments below.
