I didn't realize I hadn't dropped by your sketch book yet, rude much >.<
anywho- I quite like your character drawing- & your life drawing has a great movement to it- you've definitely got animator blood

.
I was in the same boat as you when I did my first gouache work. Where I grew up all I could get was house paint and acrylic from the Walmart craft section.
Gouache gets to be a lot of fun because it can be used like water colours, or thicker like acrylics, or a hybrid of the two.
My teacher made us do lots of exercises in learning how to use the paint- usually we just taped off 9 squares on a watercolour block and experimented.
Personally I find it works best when it's dried into a rock and I treat it like the cheap tempera paints you can get at the dollar store.
You can get lots of nice gradients and water-colour looks that way.
Most of the old movies and shows were done in gouache, so there's lots of awesome excuses to watch some of the old films and look at the backgrounds.
Not as many shows still use it, but anything pre 90's is a good bet.
Makes me want to get my paints out....if I can remember where I put them...
Happy sketching
