Mark A. Nelson is an illustrator, comics artist, concept artist and art director. He has worked for Dark Horse Comics, Marvel Comics, DC Comics, Kitchen Sink Press, Wizards of the Coast, TSR and many other publishers, as well as gaming and visual development companies like Raven Software, Sega Games and Pure Imagination Studios.
Nelson has a graphic style, largely in pen and ink, that emphasizes beautifully effective line work and linear textures. In addition to his confident drawing style, the linear character of his work gives it a particular visual appeal that owes much, I think, to his background as a printmaker. The lines are controlled, emphasized and varied in weight in a way that gives the renderings a wonderful surface character.
Many of the pieces on his website appear to be for personal projects, or just the fun of sketching — and they are a treat. Nelson seems to have a endless array of imaginative creatures, drawn from a fascination with natural forms.
I particularly enjoy his ink drawings on toned paper, which are highlighted with what I take to be touches of white chalk or pastel, and perhaps gouache. Nelson also works in color, and you can sometimes find the same piece in both a monochrome and later color stage.
There are several print collections of Nelson’s work available from his website store.
