>>1880922I don't know who this character is, and reverse image search failed to give me a character name for a reference, but even so, this image is very doable, even from the Twitter post. To make the lineart not look so wobbly, you need to take into consideration using sharp nodes with independent handles. Anytime you draw a fill and meet a separate line, create a sharp node with independent handles. This will allow you to show separation of objects and is very important in minimalist art, as you don't have the lineart to do it for you. Otherwise, everything will meld together if you only use smooth nodes with dependent handles, creating many blobs of fills.
As for the coloring, I just did whatever I wanted with it, but it is still pretty simple. I wanted the coat to be a blueish-gray coloring, so I used the HSB scale, moved Hue to a value that got me to the blue range, increased Saturation to a small value to give it a tint of blue, and then decreased Brightness to darken it, but kept it at a reasonable level so it stayed gray. For the hair I wanted a purpleish-blue coloring, so I did similar steps above to reach those values. For the skin, I kept the values within these ranges: H: 25-35, S: 15-24, and B: 95-100.
Again, all of these things are very simple to do, and there really isn't much difficulty due to the original, as it is very reasonable. You just need to practice, and understand certain things that are required when working on minimalist images.
