Just out of curiosity, was this by any chance referenced from my photo: nikki-vdp.deviantart.com/art/L…
Not that I particularly mind, I always allow people to use my pictures for drawing reference (NOT photomanipulation!), but if it is the case, I'd like to advise you to post a link to the original whenever you do this. It's considered somewhat of a common courtesy here on DA, especially cause most photographers just love to see the result of someone referencing their work. But like I said, feel free to use my pictures for drawing practice any time, I'd just love to be able to see the result.
Very nice job btw, keep it up
