You know, I’m kinda new here, so I was wondering if anyone could give me some tips on how to make my art look better and be easier to use? I mean, I still have problems, so any advice would be super helpful.
(Also, I’m not sure if I posted this in the right spot, so let me know if I need to move it.)
A lot of useful info on the page @dk8 shared. As for features/methods I use often, that weren’t shown on that page:
Using Filter → Colors → Colors to Alpha on a black and white image is an easy and reliable way to remove the white color from an image, leaving only the black lines.
When using the Fill Tool, if you’d like to fill to the edges of only a particular set of layers, while on an empty layer, open the Tool Options Docker, locate Reference and select the icon that looks like a small tag. This is the Fill Regions option. Once selected, you’ll see some color swatches appear. Go to the Layer panel and then right click on one of the layers, and you’ll see those same swatches at the top of the menu. Using whichever color you’d like, set each layer you want Krita to see while you Fill, to use that color. Then set the Fill Tools reference color to the same. Now, when you click on the canvas with the Fill Tool, Krita should color to the edges of only the opaque edges of those layers.
Instead of going to the Filter menu and applying a filter from there, try using Filter Masks or Filter Layers (they are two separate things). Filter Masks focus on the layer you set it to, while Filter Layers stand alone as a layer and affect any layer/group beneath in the layer stack. In both cases, however, you can apply many of the filter’s effects, while keeping them non-destructive (so, at any time you can return to the filter mask/layer and change/remove the effect). For example, if you wanted a layer to have motion blur applied to it, you could set a Layer Mask on that layer that used the Motion Blue effect. If you later decided you had applied to much blur, you could just return to the layer and edit the blur level.
