Wow, just one day offline and I got a lot of feedback.
Thanks to you all for the kind praise.
(Although when I now look two days after on the photo I must admit, that the fur structure on the female does not look as fine grained as on the orginal figure ...)I sooooo love these customs!!!!
And the presentation is just superb! 
That photo would make a great desktop wallpaper (hint, hint!). 
Okay, I understood. Please give me a hint when I forget to send it to you in the next days.
I've often thought of trying to make a female partner for the Caveman Special, but I'm sure I couldn't have done it as well as this. 
I assume, you would

When I'm looking at you customs (e.g. the Santa Babe) I think this would be no big deal for you

Top marks for doing such a good job of matching the tanned skin tone. May I ask what paint you used? A combination of colours, I'm guessing.
Right. I'm using the Revell enamel paints (although lately I also tested some of the Revell acryl paints); in this case it's actually a combination of color (don 't ask me how long it took 'til I found the exact match ... and don't ask me which incredients I used

-- it was not that easy because the head and the legs do directly fit to the painted pieces so the shade must be as much accurate as possible because it would be visible very clearly if not)
Have you considered sending photos of some of your creations to Playmobil, Jochen? 
No, I never considered this. Do you think I should? (Aren't they reading here anyway ?!?

) But on what should I hang the story to? As enhancement requests? Suggestions for new sets? Or just the simple storyline "your stuff is so lovely, look what many nice things can be done with it" ...

But as longer I'm thinking about it, maybe I actually should do it. Currently I have some customs in work which would be actually a good suggestion for add-ons. (Hm, maybe the badminton set too, or ...)
