It depends what program you are using, but maybe consider coloring your lineart or withdrawing the opacity til its blended.

I do color it now but I could try blending that way o.o
Thanks!

you an also try something like a soft Gaussian blur, so the edges aren't as sharp. and set it to darken, rather than normal or multiply.

I could try, but would images come out looking dark? o.o

do you keep a copy of your lines on a separate layer? What I do when they look too sharp is to create 2 copies set to darken, blur the bottom layer by .5 to 3 pixels--depending on DPI--and set it to 75% (-ish), then set the top (sharp) lines to 25-50% darken or multiply. It gives a softer edge and you can play around with the settings to make sure they don't get too dark. And if you have some sharp highlights near the lies, you can go in with a mask to erase any bleed-over until you get it perfect.

now, off to find my

That's an interesting technique O.o Thanks

Waaayyyy too many years of working as a graphic artist has left me with a lot of funky techniques and work arounds. Try it and see if it works for you. If it does, cool. If not, store it away. May work on a different project in the future. Now I must away to get my car's emissions inspected
