ive worked with glass in my glass tomatoes post and i see a few things that can help bring out the effect! give the glass and the liquid inside it a little more color, you wanna make it look dramatic! The way i did it was copied the liquid area of the ball and covered it with a more drastic gradient (very light color to very dark color) then i set the mode to overlay. The only other thing i would say is that glass is see through so take the other balls and background that is behind it and make it look like theyre visible through the ball (in my image i didnt do this step) and finally add some shiny streaks! very good start though and i hope you find this helpful

There are four kinds of lighting: ambient (colour), diffuse (shadows and highlights), specular (glossy reflections), and emissive (glowing).

For glassy/shiny objects you need the first 3, but your drawing only has the first 2.

Also, to make a hollow glass ball, you will have these reflections on both the inside and outside.

Here is an example showing the missing specular lighting:

and the same with the layers spread apart to show the different lighting:

The last thing glass needs to look realistic is refraction (distortion because of bending light).

I took a quick photo of liquid in a wineglass since I don't have any glass balls handy ;)
