Looking great. The contest mini is very nice. I like the technical paints from GW except the blood. I mix my own blood from Tamiya clear red with splotches of partially mixed in Vallejo smoke and it makes varying levels of red and dark red for splashes of blood and drying, sticky blood.
A thing I do with washes (because I love using them too) is after the wash is dry, I come back with the original colors and highlight over the wash. It is a simple and fast step and makes the wash really work better IMO.
Keep it up!
