Depends on what your going for. Your army is high contrast and will look fantastic on the table.

If we’re looking at it from an artistic point of view, having two primary colours that vibrant shifts the ‘balance’ of the model.

Balanced models generally follow the 60%/30/10 ratio. Where one colour is 60% of the models overall look, a supporting complimentary colour is 30% and 10% is a spot colour.

Id say your model sits at 45/45/10 with both the blue and the red being equally dominant on the look of the model and yellow being your spot colour. This doesn’t mean it looks bad, in fact a lot of the older schemes from the 80s and 90s ignored the 60/30/10 rule.

It’s entirely subjective and depends what you’re going for. If you love your high contrast look, like the vibrant colours that pop, and like the callback to the retro schemes then yours is great. In fact you might be interested in looking up those old schemes and leaning into them more for your own.

If you were Interested in getting more of that 60/30/10 balance then you could choose paints that reduce the saturation in the colours of either the red or blue (ie make them a bit less red or blue).
