I am glad I did it and am really looking forward to getting in some more practice! I've never had any kind of training in this area...I did try to once but I fairly sure my teacher hated me, EVERYTHING I did, in her opinion, was wrong while the rest of the class was perfect :/ So in a nutshell that didn't last too long. Maybe I'll try going through professional training again one day but definately not at the same place!
I'd done a few drawings for friends in the past, I found copies in a folder on my computer recently and had almost forgotton I'd done them at all!
I was a bit taken aback at first, I had a moment of 'did I really do that??'. I will definately be striving to get some more practice in and hopefully even start selling some custom portraits!
