I don't know which artist needs to hear this, but if you don't like your lineart...if you find that the lineart stage does not add any value to your artwork...then you do not need to do lineart. your artwork is still complete if you go straight from sketch to colours. as long as you think it's complete.

The same goes for any stage of art making. does shading not bring joy or improve the piece in your eyes? then you do not need to shade! some art styles genuinely look better without shading!
