Hey, impressive work getting rid of the under sketch. This looks really good.

Thanks again for doing this for me. Glad that there's someone like you out there that's willing to color in something like this. I've been trying to learn how to use a digital art program for about a week now and I now understand how difficult it can be just coloring in a preexisting sketch.

Yeah. Granted I don't know all the tricks and speed techniques yet... if I have a lineart/sketch with everything on one layer, it takes probably 2-3 times longer than if I had the PSD.
Cleaning up sketches w/out a PSD is the worst xD; The one I did for Synli here took like 1 3/4 hrs just to get rid of the sketchlines and redraw some lines to make it a cleaner lineart orz
But it gets better as you learn some tricks. Your sketch for example, since the extra lines were a red color, I played with the brightness/contrast and they literally just disappeared~
-I use PaintToolSai 2 if you're curious

I've just been using Krita since it's free, but since it's just for practice I'd probably never upload any of my color-ins. Plus I may have downloaded some linearts without permission, so there's that reason too.

You can color other ppl's stuff if it's just for practicing. But you can't upload/share it or use it for other works.
