The first time some of my friends did see my 28mm miniatures I was still using Humbrol and in the same fast way that I had been using it for 1/72 and 15mm, it was before internet and I had no idea that any shading or washing or whatever could be expected.
They looked politely and said nothing.
Some time later I overheard some mumbling about painting with a paint roller.
It was many years ago and I’ve been trying to improve. Not really succeeded.
