You can see it that way. It is also a way for me to improve on my drawing skills. Sometimes I also arrange giveaway events where I choose a few of my followers and I draw a portrait of them for no cost. Then after encouragement from @surpassinggoogle, I have decided to start this steemgig - portrait drawing, it also gives me an idea of how much people are willing to pay for portraits, and then eventually I may start setting a fixed price. Hope that makes sense. Let me know if you are interested to get a portrait. Have a great day!
