Your artwork falls under the category of 'Primitive', Naive or Outsider art and is similar to the works of famed artist, Grandma Moses. If you are a prolific painter, meaning you have a high output of work and find you cannot stop the creative flow and consistently make paintings, then you could potentially create a decent following of collectors over time. Since you are located in the Bronx, I highly recommend attending the yearly Outsider Art Fair, which is happening quite soon, Jan 18 - 21 in the Met Pavilion. Seeing what is being offered and meeting the dealers may help further your art endeavours. The estimate is based on the current prices for contemporary, naive and primitive folk art works by unlisted artists.
