Mini's too small. The Highlander IIC is a little lanky with it, but looks great. The legs of the mini are short and stumpy; the body chubby; the right arm gauss rifle is a small beehive stuck on the wrist.
Yes, it matches the old TRO art, but consider the cover of the Northwind Highlanders supplement:
The current mini, with straight legs, is about as tall in proportion as the toilet-squatting Highlanders in the cover. This suggests longer legs, and longer arms (increased for both upper & lower arm sections) would be ideal.
I've made a few modifications using that high-tech tool, MS-Paint, to give some suggestions about what I mean, see attached. Changes are:
1) Legs lengthened by 20% in side view
2) Legs lengthened by 20%, and both legs and hips thinned by 10%. The leg thickness probably isn't an issue, but the hip section looks a bit big.
3) Inserted a second "upper arm" segment to each arm
4) Pulled the gun-shield on the right arm out 20% to extend past the muzzle
My 2 cbills worth.
