Okay, first of all, only some of the extant Tintin adventures are in Herge's style. Herge was, initially, a cartoonist for a Belgian newspaper entitled Le Vingtieme Siecle (trans. the 20th Century), for which he created Tintin adventures. Tintin was envisioned as a travelling correspondent for the newspaper's cartoon supplement, Le Petit Vingtieme (the little 20th) and Herge's cartoon strip portrayed Tintin travelling around the world and having all sorts of kooky adventures, which involved a combination of slapstick, situation comedy and social satire and commentary. The first adventure saw Tintin travel to the Soviet Union, subsequently to the Belgian Congo, and then to the USA. The first adventure is only available in Black and White, and in it, you can see Herge's initial crude style. This same black-and-white style was retained through the first 3 adventures, though the style gradually improved. The next 6 adventures were also initially published in the same format, in black-and-white, though the style gradually progressed and improved, as did the content and quality of the stories. These strips, after their initial publication, were republished as books or albums. In the middle of Tintin's 7th adventure, the Nazis invaded Belgium and siezed control. Herge discontinued the current Tintin adventure, because it had politically charged content--most especially, the villain was a ruthless German character named Dr. Muller. He began a new adventure, again, in black and white. After the war, the pre-war Tintin adventures were republished in the current format--some of them were even completely redrawn--but not by Herge! They were redrawn by Herge Studios--mostly by Herge's collaborators. The incomplete adventure that was broken off by the Nazi invasion was also redrawn and completed. These new publications of the adventures were in color, in a new, slicker format. The books were published by Casterman. Herge then started a new magazine featuring French language BD (i.e. bande desinee or cartoon strips) called Tintin Magazine in which he began publishing new Tintin adventures--something like the equivalent of 2 pages (from an existing album) every week. Again, these were in color and in the new, slick style of Herge Studios. In other words, Herge himself created the rough story and did the preliminary sketches. The finished artwork was executed by his assistants, who are really responsible for the look and appearance of Tintin and the supporting cast, as well as the appearance of the cartoon universe they inhabit, to a substantial degree. Compare the two styles--Herge's original style to that of Herge studios--and the differences are clearly apparent--especially in the appearance of Tintin himself. My point here is that Herge's "style" is really not exclusively his own, but that of his collaborators as well. The collaborators are partially responsible for the characteristic style in which Tintin adventures came to be famous and appreciated world-wide. As such, the collaborators deserve their fair share of the credit, I'd say, and even a say in whether Tintin should continue or not. They deserve their fair stake in Tintin, and the privilege of continuing his adventures, in my opinion, even though the originary creative mind has passed on.
