Here's a good example of design exploration based upon an established direction. Fernando Munoz studied at the Academy previously and has returned this semester to further enhance his character designs skills. The samples you see here are variations of a theme he's developing for his current class assignment.
Fernando displays solid drawing and good design as he works his way through the different approaches he has in mind for his character. In fact, he can develop several characters for his theme from the sketches he's done so far. There's enough variety to lend themselves to an assortment of individual characters in a array of slightly differing stylistic approaches. Looking forward to what's coming next from Fernando and his project.
