digital color on pencil drawing

Hello everyone, i colored another one of my ball point pen drawing today. i think blue and fiery red colors blend together perfectly.
its colorful with a lot of dark strokes and i had a lot of fun working on it.
i chose those kind of colors for the face because it makes the drawing look more attractive and catches the focus of the viewers.
i do think that the teeth part is looking a bit weird, i should have just drawn a closed mouth but it is done so i have go with it now, even though the teeth is extremely white( not a good look).

here are some process shots:
