Oh my,
The good thing about your painting is that you're so enthusiastic about it. That's a good starting point. But all we have for the start....
You need to learn almost everything - starting with proper preparation of miniatures (isn't it a moldline on the powerfist veteran's leg?), proper way of applying paint and controlling its flow (no, drybrushing may be good for fast painting of armies, but unless you are a experienced painter keep away from it when painting a normal miniature), learning precision of your brushstrokes, learning to add more contrasts...
Now you can make your miniatures colorful. That's not bad, but we don't have much more to improve yet. We need to return to the very basics.
So the first steps would be:
1. Take one PLASTIC miniature. They're cheap and much easier to prepare for painting. They are much smoother than metal minis and less detailed. That's great for now. A plastic space marine will do.
2. Basecoat it WHITE or PALE GREY. It will make it easier to cover with any color, including difficult colors like reds or yellows.
3. FORGET about drybrushing. Completely forget about it! Learn to paint with wet paint and apply details MANUALLY - trust the manual placement of highlights, not random dry brushstrokes.
4. Take one color you feel comfortable with. It can be blue, red, yellow, green. Keep it clean and bright.
5. Thin the paint slightly and color all the parts which need to be painted this way. Make it neat, make it smooth, make it flat. Don't let too much paint to stay in the recesses and cover details. Move on to other colors. For now paint NO details, NO highlights, NO shadows. Flat, neat painting.
show us if you can do it.
if you can, then move on to:
6. You know Polish and so go to the Polish section and read Gildor's thread. Read all the advice he was receiving, especially focus on the exercise we gave him: the one to paint a miniature with flat neat colors and SIMPLE but CLEAN edging and darklining.
7. Do the exercise.
show us the results.
if they're good - we'll move on to contrast, detailing and color theory.
you will be on the right track
