My sitter and my drawing by Dmitry Shaklanoff-von Seipt

Great skill Dmitry.

Good drawing Dmitry - your have some really good portraits in your portfolio. Looking at your gallery, I hope you will not be offended if I comment that you would do well to use an app. to brighten your photographs. White paper never looks right in photos unless you do a bit of editing. Your camera thinks that the white paper is an area of overexposure and so darkens the whole thing down. It may be possible to increase the exposure in the camera, but I find it better to edit after the photo is taken and increase the contrast as well. Best of Luck
