What I've made so far with only using the Italeri WoT ling (incl. their paints) is the following:
I did the crusader first, and decided to try and weather it and probably went a bit overboard. I used a wash from "Army Painter" to try and give it some weathering. One day I'll redo the road wheels as they aren't painted particularly nice (or evenly for that matter). But since this was my first ever attempt, I am quite happy with the result.
Second tank was the Sherman, and here I was surprised at how dark the Italeri OD actually is. It is the same brown as the actual brown included in the paint set, so I was highly disappointed by that. I was going for a more dark green shade than what I got. So this Sherman is repainted and not very well. This also needs some more love down the road when I am more experienced. It might even be demoted to test bed for different techniques and colours. https://imgur.com/ST5PVq3
Thirdly and most recently I've painted a Chaffee in plain OD. I've done some light weathering/brushing of lighter shades to give it more depth, but I have limited colours available so It's limited what I can achieve. I am more happy with this than the Sherman. https://imgur.com/VAg0YN7
I am planning on buying a bunch of pigments and washes for future projects and I might go back to these and give them some more love. Also sorry for not the best pictures. I just took what I already had on my phone
