I use all kinds of materials, all water based. Most of the materials are listed. And just stick with it. Find your artistic voice and stay true to it. Make sure you're work is cohesive and works together. You want people to recognize your "stlye"
Oh, fantastic! Your blending skills are bitchin'. I don't have the patience to blend whenever I used acrylics. I've contemplated using multiples lines to create gradients, but haven't tried it out yet (school takes up my life).
