Hey guys! So I have been secretly wondering why is it that many illustrators also double as concept artists and vice versa. Are the workflows similar or did they have to learn both trades? I am aware that they are not the same but I can't help but look at portfolios of people that are both concept artists and illustrators and having it look more like an illustration.
I'm going to use Mr. Seal as an example. His portfolio is to me, mainly illustration. But one can still consider his trade to be illustration/concept art. Why?? Are his characters and environments all designed by himself from scratch? To me concept art is thumbnailing ideas after ideas like illustration but it also has to work from many angles depending on what the art director asks for. And while the finish product of a concept can be very rendered, it doesn't go to the full extent of being made "pretty" with choosing the perfect storytelling, composition, lighting, etc. In illustration, are you left to design your own characters and environments/scenes at times? That freedom would kind of make you like a concept artists...right? I'm in the dark ages about this haha.
So I guess my question is, where is the line crossed between concept art and illustration? I feel like the two get increasingly similar. So what really divides both of those?
