I feel a little thick after reading your painting, but the reference picture you chose is from Japan, which makes me feel a little headache.

Personally, I prefer Japanese. Let's talk about Japanese.

1, judging from the sketch, you should understand the structure of the clothes. If nothing else, just say that the outline has not changed (the hand-drawn board is not around, otherwise it can be changed), resulting in a rigid feeling. As for how to change it, copy it first (it's not bad to recite it) and then observe it more (nothing new haha)

2. In terms of layers, individuals are divided into more than three layers, such as background color, shadow, highlight and reflection.

3. In terms of color choice, I can say that this is ugly. Even if you choose this color, don't use monochrome, it doesn't look good. Personally, I prefer small fresh colors. If you can't choose the color directly, (find a picture that you think is good, have a look, and then remember to try to reorganize yourself. )

4. From a technical point of view, the effect of Figure 2 is not a simple brush effect. I will use a pen, an eraser, a blur tool, two layers of shadows (I like to change the layer to the bottom of the positive film and use the background color, which is lazy), and more importantly, it is reflective. Figure 2 simply sprays with skin color.

5. it has texture. Look at the sweater you drew. You can get some texture.

6, personal advice, copy the clear big picture, you can see the big picture of the details. Sometimes you can find the original psd and see how the Great God uses it.
