Nice progress, Kamil.
As for the shake-and-bake character, no kits are like this. WNW ones are close to it but, still, not exactly so. I have already built 22 kits of their making, currently working on the 23rd one, and every single one of them required some puttying, sanding, polishing, removal of form ejector push marks, cleaning some flash or mould-halves joints marks... Even the nicest bits from WNW kits require some preparation. And it is good. If you want shake-and-bake - go for Lego bricks :-)
