When asked if there are any special differences in his work recently, Brewster responded that he had rekindled his interest in the work of Dubuffet, digging out a couple of books that he hadn't looked at for years. Although, the influence is diffused and subtle rather than being a formal tribute or homage. Plus, as Brockmann points out, "It's all intermingled with my tendency to let the paintings evolve as I do them rather than do a lot of pre-planning that can actually restrict the spontaneity that is an important part of the creative process for me."

However, the objects and themes that populate his current work reflect Brockmann's long term and continuing focus on the positive, whether the paintings show animals, family life or buildings. He says that he sometimes puts in a palm roofed house or other architectural detail when he's stuck on where the painting is headed, and that helps him to break the impasse. That is currently reinforced by the fact that he is actually building a new house for his family, which also ties in with another common theme in his work, family life. Of course this new place will only be for summer use when the local river is too high to drive across to reach his current house, which will become the winter, dry season, house. Maternity is featured in several of Brockmann's work, and he and his wife Carmen have two young daughters, and his brother who is a neighbor has a one year old son. Even one of Brewster's large female terra cotta sculptures shows the signs of being several months pregnant.

Although Brewster´s paintings have outnumbered his sculpture in terra cotta, wood and bronze in recent years, the artist actually has a Master of Fine Arts degree from the famous Cranbrook Institute in the United States, considered to be one of the best schools of ceramics in the world. In addition to being a teaching assistant while there, he has since taught special workshops for undergraduate and graduate students of Cranbrook, as well as students from the famous Rhode Island School of Design who have come to Mexico to learn Brockmann's special low fire techniques of producing terra cotta pieces from clay they dig themselves. After graduating from Cranbrook, he received a grant from the giant Koller Corporation to be in their Art in Industry program. Brewster was able to use the iron casting facilities of this leading producer of bathtubs and bathroom fixtures to produce ancient looking figures with pre-Colombian influences. Kohler actually acquired two of his pieces for their private Museum of Modern Art.

Animals and marine life continue to be very present as themes and elements in Brewster´s work, with alligators, jaguars, dolphins and fish being in evidence, among others. This seems natural considering both the artist's residence in a jungle above a river as well as his Bachelors Degree in Biology with a minor in Botany from the highly acclaimed Bennington College of Vermont. It also relates to Brockmann´s interest in indigenous folk art and ceremonial masks, most of whom portray animals. Although this interest started as a young child tagging along with an uncle who collected, his passion eventually ended up being manifested in the form of owning and operating a folk art gallery in Puerto Vallarta, the highly regarded Galeria Olinila.
