I tried to make it akin to the second upgrade in “Battle City” for the NES.
I'm not too happy with the result. This is the last time I try drawing in grayscale first :/ I may try reworking this in the future.
I found it difficult to then choose the colours that I needed to apply. I think I'm quite lowsy on palettes. I really need to exercise more. :) Thanks for the insight mykar!
I think drawing in grayscale first is helpful in determining the tones of your work to avoid too much blending of colors :3
