Color lines are the lines that comes almost on every marker expect alcohol based. On your wings if you look them you can see (From Midle to left) First you have colored from Midle to left.Then you have stopped that line and started another spot to color bit more different angle and overlapping the last colored area. Leaving that Spotty look where you can see that the color aint evengly all around the surface.

And if you use the right type of ink on right type of paper the ink drys bretty fast. Myself i use Chinese ink on 160 - 250 g/m²

Ah, okay. I'll try to fill the areas in more evenly.

You shuld try using bottel ink and brush on large black areas. It makes the Area total black (with good ink!). and makes it look like more professional work.

I think the Center bottom one is cute. ( Remake from one of your earlier works? :) ? )
But you you could have done the wings "color lines" to follow the shape...

Hmm, you're right. I did't really want to use any this time around (mkakes a huge mess of my desk, takes forever to dry), but I'll see if I can use some today.
And what do you mean by color lines? Outline it in color?
