Thanks folks!
Been off making decisions about the next level of detail. Lots of filling & sanding. Finally taking enough shape to give a visual update.
Couple areas where I marred up the filler that will need repainting, but you get the general idea.
Thinking about an 'Arctic Camo' paint scheme, so even though this is just the primer, some of the 'sprued' plastic started life as grey, so it's actually not a bad representation of what it will eventually consist of (though a little more thought put into the placement of said camo)
Cheers!
