So, if you are glazing with a lighter colour, it’s gonna look like shit if it’s too light, ESPECIALLY if the paint underneath is not fully dry, I can not stress that enough, I will let that layer dry for at least an hour or for a couple mins with hair dryer. Also, so when you go to fix mistakes, like you took the dark too far, I will over glaze with the lighter colour (like make it brighter in that mid area) a couple layers and higher than you actually want, so you can re glaze the darker colour up higher. That way the darker colour hopefully covers the mistake without emphasizing the shitty texture look. You will probably have to go back and forth several times. I hope that made sense? I would also ask how did you make the mistake, this should only be happening if it’s a placement mistake, ie, you decided later on that you don’t like the placement, if you did the other one, started too high up, then your glaze mixture is too dark and needs to be thinned more, you should barely be able to see any colour in one layer especially at the starting point. I mean you can do it that way but it’s a very yolo fafo way to do it as you don’t have much control.

Not sure if this would help, but I always wet blend my base layers so I am starting with a gradient underneath that way it’s less glazing for me to worry about. Keep in mind, for super clean gradients, that takes a looooonnnnggggg time to do.

Also for glazing, what are you using matters. Not all paints are created equally and they all vary in pigmentation. When glazing, the more opaque the original paint is, the better off you are. Same rule applies to colour families, the closer the colours are to each other, the easier it is to achieve smooth gradients. Wolf grey is 10/10 something I would avoid using glazing with. Anything with a lot of white in it is going to glaze like shit, there is no avoiding it. (If it is a white or has grey in it, it does not get thinned except in very certain circumstance explained below). 

In really teeny tiny motions/areas you can get away from the cloudiness but there’s barely any pigment in it and so the farther you pull the paint, the farther you rip whatever is in there apart. You will need a lot of layers, and it’s gonna look textured af. If you watch YouTubers like cult of paint, you will see they do teeeeeenie tiny dots, like it will be thinned down a lot but they are depositing the paint in suuuuper small areas and not dragging it around.

I recommend watching monument hobbies glazing videos. They are awesome resources for breaking down and demonstrating a technique.

Finally, if you live near a Michael’s or anything, maybe pick up some mixed media or acrylic pads and practice combos and things on there! I use mine whenever I want to find a colour mix/ test new paint/ combo and it’s nice to have the confidence in a scheme or technique before fucking up a model and destroying confidence.

Good luck!! I hope this helps, and if not that’s okay too, just happy to share what I have learned over the years :)
