Not bad for mini number one. Best advice I can give is to put a drop of water on the paint you get out of the bottle. Sounds counterintuitive when you need good coverage but two thin coats will always be smoother than one thick one. If you don’t feel confident enough yet to put a highlight and a shade on your minis invest in a few washes that will give you instant shading then paint your base coat back over the higher points. Have you put a gloss varnish over it or are you painting with glossy enamels?
