I'll elaborate a bit more.
The good: It looks like you know how to thin paint, apply pretty even coats, have the brush control to "paint within the lines", and can edge highlight and darkline. The basing is really nice as well, well above the glue and sand that most people start with. These are all skills that usually take new painters way more than three models to get, so you're way ahead of the game already.
The next step in my opinion is to take a look at the mini and understand WHY you are edge highlighting where you are. Try to only highlight places where light would hit, rather than just any hard edge. The "any edge gets a highlight" is sort of a GW style, it's a bit old school and is fine if that is what you are going for, but try only doing the upper-facing edges and not, for instance, the bottom of the leg plates.
Wet blending is not for everyone - I can't really get the hang of it after hundreds of minis. You can try glazing - thinning paint down to where it's very translucent, like colored water, and applying it thinly to gradually shift the color. You can try that with black or a darker blue on the lower legs, undersides of the arms, etc. You can do the same with lighter colors on upward-facing surfaces, but it can be harder, as lighter colors sometimes go chalky. You can use glazes to blend, too - just put in your shadows and highlights without worrying about blends, and then go over the "borders" with a thin glaze of a color halfway between each, until the line blurs and it looks blended.
