I need to improve my colors

on paper I just want to make the colors feel more neat, tbh i just scribbled in the colors and just did some shading, and some of the lines are a little wonky, idk how to improve them, sorry for the image quality

ok I don't have any advice (I suck at colors even more on paper ) for this so sorry about commenting here
But I hecking love that, that is amazing, the combo of blue and red paired with the orange is soooo good and while there are some fixable lineart it looks really nice, and I think your lineart for the black guy (I forgor his name) is really spot on
