hmm getting better slowly but surely! i would harden the brush you use for color/shade to match the solid lines tho, as well as shading with a little less grey
as in use a darker but also more saturated color to match the base color, e.g. more orangeish hue for yellow, more royalish for true blue, etc. so the shading and color pops out a lot more. i'd do some research on that or look for a few tutorials for more depth, those would explain better than i can
definitely an improvement since the last one i've seen, keep it up 🅱️
