I'd be very glad if somebody could evaluate my IELTS writing task 1

The charts below show the number of Japanese tourists travelling abroad between 1985 and 1995 and Australia's share of the Japanese tourist market.

The bar chart illustrates the proportion of Japanese visitors to foreign countries within a 10 year period, 1985 to 1995, while the line graph gives information on Australia's market share of Japan's tourism. Units are measured in millions of people.

Overall, the number of Japanese travelers showed a steady increase over the period given, besides 1991, becoming almost four times higher in 1995. Similarly, Australia's share of Japan's tourist market rose marginally and skyrocketed in 1994, even though there was a slight fall in 1989 and 1995.

Regarding tourists coming from Japan, those began at just over 4 million in 1985 and grew gradually until 1990, when they surpassed 10 million. However, a minor decrease can be seen in 1991, as Japanese tourists were just above 10 million. Despite this, their percentage started rising again in 1992 at approximately 12 million, before reaching its peak of nearly 16 million in 1995.

Meanwhile, although Australia's portion on Japanese tourism started at just 2% in 1985, it increased steadily throughout the years and doubled in 1989. It also experienced a downward tendency at only above 4% in 1990, but a ceaseless growth is observed afterwards, hitting the highest point of just over 6% in 1994. Nevertheless, a mild deduction at exactly 6% is noticed in 1995.
