Personally I don't like lots of filled zones unless that really are necessary, but that's a fairly minor point.
several other points: Do try to put your connection pins on the edge of the board. It makes wiring up much easier. You could also consider some form of connector. How are you going to mount the board? Some hardware mounting holes might be useful. The tracks to the pins look rather thin. Thin tracks tend to lift when soldering, also a small speck of dust on the film can cause a break in the track. Using a thicker track will help in both cases. On single sided boards, don't be afraid to use a few links it makes life MUCH easier. An Easy way to do this is to treat the board as double sided, and use the top tracks as wire links. Beef up the vias to a suitable size to take your wire links. Obviously you need to manually route this. I'm not going to comment on the actual circuit as I've never used this device.
