Paper prototyping. Its a fun and quick way to try stuff out.
The basic idea i landed on with the paper prototype.
Blocking in with polystyrene sheets.I layered them so i could sand into it and get a rounded shape.
Second pass adding more polystyrene and sanding the overall shape. the hip joints are from lego Bionicle .My go to for sturdy flexible joints.
In order for this to stand i decided i wanted to weigh it forward and give it some sort of toes to keep it upright.
You can see toes i ended up going with .simpler and fit the theme better .You can also see the where the back toe showed up .It later became a back wheel.
Scratch building the rear box from polystyrene and doing some sculpting with 2 part putty.
How the wheels fold up.
The nuts i used for weights i used as an exposed detail .I thought they looked like cool armor plates.
Adding small details and doing a bit of putty and sanding work .
Hand primed using Vallejo grey primer.
First pass using acrylic paints.
I used the WW2 British Matilda tank paint scheme as inspiration.
Free handing a logo on both sides. A little trickier then i had originally thought :)
Grime and washes!
Chippin and drippin!
Final with dry mud and splatters on the lower half.
