Yup those lines that you think are tiny the model really show up on the pic! Back to the mould remover tool...Good point about the soapy water too. I think this technique with very thin paints really needs the model well prepped, so I'll have another go with some other Nobz I'm painting.
For an improved finish you can try to do "prep" work before painting and priming the miniature... that is to remove the "seams" or mould lines that remain on the miniature after the moulding process. Just like the one you got on the right arm/claw of the orc, or the one that appears on the human skull. Then you can wash the miniature with soapy water so it will remove any grease remnants wether from the moulding process or from your fingertips. I am saying this because just below the "blurry barrelgun" ;) you can see a weird pattern on the green paint that maybe caused by those greasy remnants that I was mentioning.
Anyway keep having fun ^^
