Excelent work there, Mr. C. It is always a pleasure to see how well you have maintained that certain style of classic oddball zanyness to your respective characters and the like. One can pretty much tell what the standpoint and demeanor each of these guys posess are executed just by their overall mood and attitudes that are expressed in the examples shown here, right up to the finished piece.
It's true that everyone has their own way of defining their craft and skills in illustration and design and you have definitely demonstrated that factor effectively with keen precision. Just keep at it and you'll do just fine in the long run. Congratulations.
