Hello! Thanks so much for the kind words!
There are LOTS of illustrators that have inspired me. Quentin Blake is certainly one of them. A few others would be André François, Arnold Roth, Martin Handford, Jean-Jacques Sempé, Ronald Searle, Joann Sfar, Shel Silverstein… I could list dozens of them!
I draw almost everything on paper with ink and watercolors, though I’ll sometimes sketch illustrations out digitally before I sit down to draw and paint everything. I wrote a bit about my typical process over on my blog: http://philintheblanks.com/blog/?p=643
