Awwwww.... I... am.... so.... sorry. Everyone has a life they carry on by there loved ones. Your grandmother will be another Angel watching over you and protecting you from harms way. She will always be in our hearts. She is in a better place now anyways were she can frolic in fields freely and see her parents again.
no one really knows what happens when people move on, so she may still be watching over you. wherever she is, i am sure she loves you. keep strong and keep going. your painting is beautiful, and your grandmother would be proud of the beautiful pieces you create.
