ty for advices im working on a most simple thing

You should make a better scene and apply the textures correcly, this will improve the render by a great amount. The glass texture looks really nice tho, can be quite hard to execute unless you are using premades.

Try to experiment a bit more with the lighting, background and textures.

and the straw looks blurry i'm not sure if its meant to be or not
