I'm really pushing myself these days to go for much more defined brushwork and much crazier colors.
It's pretty challenging for me as I am always inclined to tone down and go to more desaturated pastel colors. In a lot of my paintings so far, those with bright colors are usually painted first with pastel tones, and then only brought up to speed with a curves modifier or something.
Working directly with such neon colors is a whole other world for me, but I like it very much. I also went back to the basics and toned down a lot the amount of brushes I use, this is mostly all a simple round brush, although I did use some more complex textured ones here and there, but they're scarcer, and it's more for really effects.
I also wanted to do some nutty perspective like this for a little while.
I included here some steps I go through when sketching!
PS: The Kanji on the stick means "face".
I struggled in the beginning to find colors I really liked, and so I used a lot of curve modifiers and other color balancing tools to fiddle around.
What I also do sometimes is add an RGB noise texture, and scroll through blend modes to get wacky results.
