If you're serious about wanting to get anywhere near good and not just fucking around with paint for shits and giggles, I'm going to have to be honest with you. You're bad and you should stop working with colors until you're solid in grey scale. Stop painting until you're half decent at drawing.
As a beginner you have none of the skills you need to tackle color and painting, and no experience and capacity to understand the issues involved. You have to start learning the basics, otherwise you will be stuck struggling with problems that exceed your current comprehension. You have to simplify the challenges you're facing and start training in a classic manner from the beginning, or you will remain confused and directionless forever.
Get a lot of cheap paper, basic pencils, kneaded erasers, sanguine sticks. Get one of these cheap fiberboard drawing boards with a clip. A3 is a good paper format for beginners, not too big not too small. Torrent Glenn Vilppu's instructional videos, learn from them (thepiratebay.org/description.php?id=7409774). Do it concurrently with drawabox.com exercises. Don't just blindly follow the instructions, you have to study and understand this stuff.
Make a training schedule and follow it. Don't get stuck on singular exercises when you feel you can't get a "good enough" result out of them. Complete the tasks you have scheduled for yourself whether you're satisfied with the results you're getting or not. Unfortunately drawing is an arduous and thankless skill to train, improvement can only be gained through repetition. Most of the resulting drawings will inevitably be disappointing and there's no way around it. The skills can't simply be improved by focusing 200% of effort on making single pictures and then spending forever trying to correct them. Finish the practice you start, note what needs improvement, and be ready to do it again tomorrow, as many times as it takes.
This is not a complete or universal "get good" plan, it's only a bare bones starting advice. When you earn some basic skill and knowledge you will start noticing these guides aren't covering everything you want to learn. There is an abundance of learning materials available and once you have an idea of what's what in the art training world you will be able to find more on your own and tailor your studying plans to your own needs. Until then you have to go bPost too long. Click here to view the full text.
