Finally found some time to finish of the Tigers. The weathering is a combination of pigments, washes and drybrushing. I don't really have a system but some of the pigment was 'knocked back' with isopropanol on a cotton bud.
After what seems like an age I finally pulled my finger out and got started on the infantry for my Flames of War Germans. I have 5 platoons to do in total (3 Grenadier and 2 Pioneer) plus associated support ie HMG's, PAK 40's etc.
