Hello,
Seawarrior ...

Your Scotsman concept is excellent. Good choice of Playmobil parts.
You might want to try "masking" the areas that you want to paint, so that your edges are a bit sharper.
Also, have you thought about trying the pinhead technique for buttons?
The master customizers use a lot of tricks to make their figures look so good.
Anyone can learn their "tricks." All of us are happy to help you ... if you want some help.
All the best,
Richard
