For not having a tripod you have done nicely here.
It’s always a struggle to shoot in low light but with camera sensor technology improving all the time it will only get easier in the future.
I understand your image a little better now. It’s quite fun.
You are in bangladesh correct?
If so and if it’s safe there is quite a bit of interesting culture and people to shoot there. You are lucky to be in that unique part of the world.
I took a look at your flickr account and you have some really great images.
Keep shooting and having fun!
