If you want it to seem like it's coming from off-side, have the speech bubble itself shoved to the side it's off of. Adjust the rest of the speech so that it'd still make sense - cut the panel into two if you must.

Another hint - if you're going to use speech bubbles (I don't), it's a good idea to keep the text centralized. Left- or right-angled text is hard to work into a circle.

Other than that? It's far better than my first try. Keep it up.
