Better pictures would be nice, but overall I’d say that looks pretty decent. There was a guy on this forum who brush painted X22 clear, and it looked superb. It can be done, and look very cool.
Spraycan though is easier and lays down thinner coats, and smoother. You can spray on the house, but it will create dust, so your TV etc would be covered in a finely coloured vapour dust. Old wife etc wouldn’t be too chuffed.
And I didn’t say all brush painting was bad. I brush paint parts of my models, most of the time you wouldn’t be able to tell. But I do airbrush and use spray cans a lot.
