Tahmina said, "In this exhibition I've put together the work that I've done outside the classes plus a few done in the classes. Most of the subjects are nature. The exhibit includes two sketches. Besides these there is a variety of media including mixed media. Most of them are on location as the ones done at St Martin's, Narsingdi and Rajendrapur. Sometimes I've been to a place for three days. Out of the lot I've selected by best efforts. I've also concentrated on the subject of the effect of light and darkness at night. A known place becomes unknown just because of the effect of light and shade. The difficulty with the night scenes were getting light for me to work in while bringing in the darkness around me. The oil work is to bring out the variations of green during the rainy weather."

In one of the paintings the light is seen though the foliage and is scattered. The play of the light on darkness fascinated Tahmina enormously. There was a lot of yellow and green against the brown, gray and black. Another painting brought in the rain on the road at night. The lights of the shop are reflected on the watery road at the side on which the rickshaws toils. The rickshaws are black and gray while the road is a sweep of gold touched with variations of hues. The shops appear like bars of gold and green.

A mixed media brings in the light under a tree. It is in mauves, pinks, browns and blues. Another watercolour, done quickly, brings in sheds and bushes with light streaming out of a shed. Bringing in the dry pond in the Department of Fine Arts is another subject for the artist. One sees this focused against dark leaves.

The watercolours are done at different spots. "Working in spots has its problems and its pleasures," Tahmina says. Watercolour is a difficult medium to handle. Most of the watercolours bring in boats, the sea and the sky, with some inclusion of boat people. She has tried to bring in the movement of the boatsmen and their boat, as they rested and then got ready to go back into the sea. At Shariatpur, while waiting at the launch ghat, she did a painting of fishermen.

One of the pencil work had won an award and the other similar work had taken her about a week. The oil series was a play of the variation of the green colour in nature and each of the painting took Tahmina 25 days to complete.

Tahmina has won the Shahid Nona Miah Award in 1997 and the Shankar Award in 1995. She has taken part in nine group exhibitions.
