I like the color hues and the elements in this one but the composition suffers. This could have been much stronger if you centered the glass with the escaping bubble in the frame AND had the circular object in the background more in the frame such that you see it's full curves on both the right hand side and left hand side. If that background object showed it's full curves on both sides the viewer would more strongly connect it with a spherical object and thus it's connection to the escaping bubble in the glass and bubbles in general would be fully realized.
