So does my 12K

Love the GUO did you follow the Warhammer TV tut? It's a pretty fast model to paint, I really like the extra detailing on the guts.

Try adding some medium to your shade just a drop to thin it a tad or you could use some retarder to slow the drying process, don't overload your brush. Sent from my iPhone using Tapatalk

What did you shade the gold with, Seraphim sepia?

To stop the tide mark water the wash down more with Lahmian medium and apply a couple of coats, regarding contrast don't be scared to go bold with your highlights, a tiny spot highlight will make the viewer focus on that part so use it to draw attention to a particular area. You don't have to use green to highlight green, experiment on a test model, using say yellow, white, orange will add a dynamic to the model. Experiment is the key. Watch lots of videos from different painters and find a style that suits you and copy what they do. W&N Series 7 are my goto brush they are amazing, expensive but worth it. I think you have done a very good job so far and pushing yourself is a very satisfying aspect of this hobby, keep it up.

They look really good I especially like the pipe, any ideas on colour schemes?
