Hi, great tutorial so far, I am a professional illustrator specialising in aeronautical illustrations and am published monthly. I use the Adobe CC suite as well as a bit of CorelDraw in my digital work but my freehand work is what I love the most and for that there simply is no better marker than Copic. I work my markers very hard on a variety of substrates and surfaces and have never had a tip failure or malfunction...best of all I can just refill them when necessary. The cost here in South Africa is a little prohibitive but I include a little fee in my invoices specifically for markers, the way I see it if I was a surgeon I would need instruments to be effective, as an illustrator I am nothing without good markers. A question I have would be which markers would you consider as the best alternative to Copic in terms of price?
