Hi Teoh,
I just want to thank you for one of your gumroad courses (on Concepts) It was every bit as informative and understandable as all of your work however for me this course proved it wasn't the app for me. I followed along step by step as you walked me through it and by the end I knew my needs weren't being satisfied by this app. Thank you again , now if you can get your head around HiPaint I'll look forward to you sharing your insight
