The very talented illustrator and cartoonist Phil McAndrew wrote an article called “Super Obvious Secrets That I Wish They’d Teach In Art School" and I think it’s definitely worth a read. There are without a doubt some very astute "words to live by" in there - this bit proved especially true for me (in regards to self-promotion): "The most effective thing I’ve done has actually been the simplest: Draw awesome stuff and put it on the internet. Do this for a while and good things will happen." Phil also has a tumblr, which you should all follow! Enjoy!
I’ve been getting a lot of questions again about what tools I use (specifically the brush pen), and I wanted to remind you guys to please check out the FAQ section - therein a complete list of the tools I use awaits you!
