Looking great, those are an improvement. Yeah, White knight is right to point out the yellow bits. I find it is usually the bit where the blue meets the yellow on the roll. I generally cut the strips into 1cm lengths and then when I use them, cut them into 3 sections, the yellow, the middle (about 2mm wide) and the blue. This gives you nice, fresh greenstuff to work with.
The dwarves look great too, the Elephant beastmen look nice. Any update on those guys?
