Artist description from Pixiv:
Krita 5.0 - 5.1 的启动图。这张启动图最初的灵感来自莫奈的《打阳伞的女人》。2020 年底时，我发现 Krita 会在高分辨率屏幕上显示高清版启动图，但之前的启动图细节太少，无法撑起高清画面的排场。多年来我一直强迫自己不去堆砌细节和特效，而是专门训练形状和色彩的基本关系，但由于高清版启动图的需要，我决定重新启用复杂的技法。在这一版 Kiki 的设计中我着重强调了她作为机器人的特点，让她“电子松鼠”的称谓得以名副其实——所有的关节均采用机械结构，并大胆地呈现一部分连接部位的框架，头发、耳朵的花苞、尾巴、连衣裙均采用半透明的塑料材质，强调她的人造本质。

English Translation:
The startup screen for Krita 5.0 - 5.1. The initial inspiration for this came from Monet's art "Woman with a Parasol". At the end of 2020, I noticed that Krita would display a high-definition version of the startup screen on high-resolution screens, but the previous startup screen lacked sufficient detail to support such a high-definition display. For many years, I have forced myself not to pile on details and special effects, but instead to focus on training of the basic relationships between shapes and colors. However, due to the need for a high-definition startup screen, I decided to reintroduce complex techniques. In this version of Kiki's design, I emphasized her characteristics as a robot, making her nickname "electronic squirrel" truly fitting—all her joints use mechanical structures, and I boldly revealed some of the framework at the connection points. Her hair, ear buds, tail, and dress all use semi-transparent plastic materials, emphasizing her artificial nature.

Krita 5.0 beta 1 is out! Now I can post the new splash I made for Krita 5.0. It was originally inspired by Monet's "Woman with a Parasol". I tried to emphasize Kiki's robotic nature, experimented with translucent parts and costumes. I hope you like it!
