Great Britain coach Mark Clark has warned the rest of Europe his team only scratched the surface of their potential in their 72-66 EuroBasket Division B win in Estonia.
"Any away win in Europe is always huge, especially when it is the first game of the campaign," he told PA Sport.
"There were no real problems, we can only just get better. Our defense can always improve and we could be a bit more together as a group, but that's what you get when national teams come together.
"We are always going to ensure we make it as hard as possible for whoever we are playing to function, that's what the performance last Saturday was based on and that's what the whole program is based on."
Stefanie Collins and Rosalee Mason each poured in 17 points for Great Britain.
Great Britain look to extend their solid start to the qualifying campaign against Luxembourg on Saturday in Cardiff.
Luxembourg suffered a 77-61 defeat by Portugal in their opening game.
"We have to be very positive about the Luxembourg game, they are coming off a defeat to Portugal," he said.
"We've got to look to put ourselves in a strong position and get another win."
"Their style of play is that they try and be very quick, even though they are not very big, they shoot the basketball very well, hit their three-point shots very well and that is something we're going to be keen on in training this week.
"We have already improved in training since Saturday.
"People are starting to trust each other more and a win on Saturday obviously helped that, we've moved forward and we are moving in the right direction."
