I try to stream every week through YouTube (link above) and Facebook. You can view the playlist above by playing the video, and selecting the drop-down list on the top right of the video. There are various live workshops featured there. I made these accessible to everyone, and we have a nice little community now on Facebook:
https://www.facebook.com/groups/watercolourmentor/

We also have a larger community where you meet and learn from other artists here:

I take requests too, so please let me know if you want to see me paint something in particular!

Thank you :) -Darren Yeo (Watercolour Mentor)
