The dates are a little loose, but here's some selections from my Photobucket. Open the spoilers at your own risk because I ran long.

2012 - this was baby's first year with her Intuos! I entered my first WAR and got into some Original Character Tournaments. I was still experimenting a lot with PaintTool SAI.
Spoiler:






2013 - more experimentation! I really wanted to master digital painting, and did a lot of it, mostly for URPG and GCeA purposes. I also started on the concepts for my Spark comic project that I'm still working on today.
Spoiler:















2014 - lotta art. This year I was less focused on technique than I was on style; I worked a lot to diversify my characters in terms of everything from race to body type to expressions and I think it's really paid off! The WAR this year, and the Nuzlocke comic I'm planning for, have helped me grow a lot because they forced me to learn a good deal in a timely fashion.
Spoiler:



























I'd show you more, but this is the oldest stuff I could dig up. Improvement is an amazing thing. Some of the stuff I've made this year makes me cringe, but that's just a sign of how far I've come. Onward to 2015!
