I would not be who I am as a person or artist today if not for many influences from many places. The following is a list of ways in which I have bettered myself and you can too.
It's been said that you're an average of the 5 people you associate with most. Make them count.
Vector Friends (Slack channel created by yours truly)
Blackformat (incredible community spanning Slack and Dribbble)
Sketchdaily (great place to build the habit of drawing everyday with lots of talented folks)
I strongly believe that we should never stop learning—especially when it comes to art.
Skillshare (this link gives you 3 months of membership for $0.99)
Creative Nibbles (my own series of 60 second tutorials)
Schoolism (lots of high quality content here for digital art)
Art Camp (12-week self-directed digital painting course—well worth it)
Ctrl+Paint (high quality free digital painting education)
Mt. Mograph (amazing After Effects tutorials)
This goes hand in hand with learning. Books are an excellent way to expand as an artist and human being.
