I am writing my resume, I do average pencil drawing & documenting tags like "developer", "photographer". In this way I want to tag as "pencil drawing artist" please help with phrase this in a better way.
You could be a sketcher.
A sketch is:
a simply or hastily executed drawing or painting, especially a preliminary one, giving the essential features without the details.
(Note: do not use "sketchy", as it has a negative connotation, implying incomplete or insufficient - emphasizing the "hastily executed" and "without the details" parts.)
