Like other artists from the Low Countries such as Dirk Maas, Jan Wyck and Willem van de Velde the Younger, Tillemans moved to England.
A portrait of him reveals that he was a gentle, friendly-looking fellow, with long curling hair, presumably his own and not a wig, such as was commonly worn by members of the upper and professional classes in the late eighteenth century.
[2][4] Macro had a bust of Tillemans made by John Michael Rysbrack, placing it "in a niche at the top of a staircase in Little Haugh Hall".
[3] By 1711 Tillemans joined Godfrey Kneller's Academy of Painting and Drawing in Great Queen Street, London, stating his speciality as "landskip".
During the early 1720s, Tillemans moved successfully into the field of painting dogs, horses and racing scenes and was one of the earliest painters of sporting scenes in England; four of these works, "engraved by Claude du Bosc and published in 1723, are among the most spectacular early sporting prints in England".
Tilleman painted numerous portraits of racehorses for his patrons, among whom were the Dukes of Somerset, Rutland, and Bolton, and the Earl of Portmore.

Equine anatomy had not yet been mastered — had been hardly approached seriously — by artists when these pictures were painted, but the "different actions and postures," to quote from the inscription on the first of the series, are rendered with a skill that shows no inconsiderable advance in the art of horse portraiture.
[2] Tillemans was also a member of the Rose and Crown Club, and in 1725 was recorded by George Vertue as steward to the Society of the Virtuosi of St Luke.
Vertue noted that Tillemans was acquainted with "people of Fashion & persons of Quality" and was in demand as a painter of country-house and estate views.
