create a clipping mask on those circles, try using the same bit you used for the lines to get consistency in your tag
The dots are strange, remove em or add a clipping mask to them. Apart from that the style is nice. A real light source is missing and you could improve your depth a bit, keep up!
i Agree about the lines and the dots It's a bit to messy for my taste,,It has multiple flow etc.. work on flow and those dots and line goodfocal. gj
