Sculpting is not always the easiest thing to do, anatomy, proportions, details. . . . . .
But there is converting, using other parts, just everything in the bit box is useful if its fits.
I have bought the US SEAL from Dragon to train my painting skills, being disappointed from the fitting and some parts it just turned out in something else.
I did it not deliberately, the gaps are really that big
Started with the first attempt, still thinking to build a SEAL
Working on it, lost my focus trying out my sculpting skills
The day after, thinking on some good times with those people at Otterburn range.
Going to create one for my collection.
In the early 80’s the Belgian army still used the Vigeron as weapon, something horrible to shoot with.
I created one from scratch.
After dry fitting, understanding that I need to start over again. Its just to big for the figure
I was more successfully with the binoculars, scratch building the small thing
Until today I am still working on the figure, changing small things, correcting others. Pushing it around on my work desk or set it between the other things (to finish)
