I think that is the most attractive aspect of this application. But those features can make it very difficult to give a minute modification or do normal sketches, which is certainly a disadvantage. 

Moreover, the process of filling colors is very tricky because the thickness of lines cannot be modified and there is no filling function.

So, it is important to start drawing after deciding the object you intent to draw and the way you want to represent it. Those which can be easily created with Silk Paint are flowers, clothes, fire, water, smoke, and hair, etc., in other words, the objects with a flow of lines and patterns. And it is more appropriate for rendering flowing curved lines than straight lines.

I didn't expect much of this application because I was more interested in minute representations. But I gave it many trials for night views or fireworks on black backgrounds, animals and human figures, which are rather simple tasks, and I was able to get some interesting results.

This work I would like to introduce is the one that shows a wonderful balance of detailed hands and fantastic flames and smoke.

Now let's go over the drawing process step by step.

SilkPaint doesn't have such features as layers or erasers, so you cannot prepare a sketch for detailed rendering.

So, the method I choose is to draw a sketch first, and later cover the sketch with black lines so that it could not be seen.

First, choose a brush. From Basic Set, choose "Brightness" brush and select white color. Then draw a sketch(hand). We don't need to draw with too many details.

Considering the light source(candle light) and the direction of it(downward), render what should be light(highlight) with lines.

Lines can be straight, but I tried creating more volume in hand by adding some lines following the texture and bends of the hand. Naturally, you don't need to pay attention to the dark sides and shades (shadow).

Once the work is completed, you should remove the sketch. As I already said, Silk Paint has neither layer nor eraser. So I decided to cover the object I want to remove with a color closest to black from Color Selection.

In that way, I removed the lines. What do you think? With this only, can you see the volume? But it seems that it lacks something. How about giving a more gradation of the shade?

Let's create three different shades. I'll divide and draw the part which receives the light into the darkest, the medium darkness, and the brightest. On the part which should be lighter than the previously completed 1st level shade, create the 2nd level shade by adding horizontal and vertical lines.

Now, it's time to create the 3rd level, the brightest part. Fill the brightest part (which is nearest to the light source and receives the light perpendicularly) with white color. Note that when filling a broad place the brush could encroach on other parts you don't intent to fill due to its attributes. From my experience, the most effective way to fill a part with lines is  to apply successive small circles(spirals) little by little. What do you think? It's not perfect but is there a reasonable amount of volume in hand?

The last step is rendering fire and smoke. It is important to select an appropriate brush which could fit the property of each object you intend to draw.

For the brightest light, using “Fire Double" and “Fire with Serifs” from “Fire Set” the big flame and the small one were each created.

In the same way for the blue color, “Ice Double” and “Double ice with pattern” from “Ice Set” were each applied to the big flame and the small one.

And for the last the white smoke was created by using “Darkness” from “Basic Set” and selecting white color.

Until you get the appropriate representation of flames and smoke you want, use canceling(undo) and draw repeatedly to complete the work.

This is another work made using the same method. What is different from the previous one is in changing the color by using Sketchbook App and adding a step of white gradation(for the white part) to improve the reality. Likewise, by adding other features on the picture created with Silk Paint you can make a better work.
