@brzostek Hey, nice to see you open up a sketchbook =]
You can sketch from reference well, so that’s a good start. For the image where you tried color, it looks like you’re changing the value greatly but not the saturation as much. Try instead increasing the saturation more, the value less, and change the hue more. I did a small paint over in that image. Even though the two colors are extreme, I gradually layered the shade over the base layer. Feel free to check out some busts I created and analyze them. I went pretty extreme on the skin tones on my hexblade bust, which has a nice contrast range without dulling down the hues. It’s okay; color is hard to work with, so go experiment. Find the combos you like and understand why you like those combos. Check out the concept stuff here, too, if you haven’t yet. Great stuff in there.
