There's a better way to do yellow than straightout of the pot- Start with a dark brown and slowly add lighter colours over that- so start with scorched brown, then bestial brown, then snakebite leather. Once you have those down put your yellow on. You'll get a nice buttery yellow instead of Yellow! Yellow! Yellow!
It's more work but worth it. Oh, and nice bases!
I was proud of these figures until i saw the photos - now I can only see every glaring mistake - ah well, will do better next time.
Using close up pictures is a good way of improving the quality of your models! Once you think you're done, take the pictures and see what mistakes you made. From there for fix them and now your models will look amazing instead of great.
