Ctrl+Paint tutorials, do a lot of master studies, study digital works that show you hints of the process, try to replicate parts of it and make it look somewhat finished. Watch some good timelapse vids with a good process.

After a while of doing this you'll be able to start simple renderings of your own, let's say, render the pillow disney animators use to learn movements of torso, or a squishy marshmallow. A hazelnut, an apple, a coin. Throw in an odd material to spice it up here and there, something translucent, sticky, wet, hairy or reflective.
Work in values only, except from time to time do specifically a color study. Try to find the color, then color pick it and check how close you were and why it was off. Then you can render a spider or a bug, with the aid of minimal linework, FZD students do this quite a bit.
Limit your palettes, learn how to mix colors to get new ones, how to preserve vibrancy and avoid muddy color. Slowly expand your palettes and the complexity of your subject, rinse and repeat. Until you're a pro (and ideally even after that), studies should take up a significant portion of your total rendering time.

The key is simplicity, a logical and well structured approach to every problem.
