Classic shoot-em-up explosion

[redballoon]

I'm finishing off some sprites for a ZX Spectrum scrolling shoot-em-up game and have eventually got around to doing the explosion.
I've plumped for the classic R-Type type explosion but something's just not quite right with it and I can't put my finger on it. It looks a bit 'wobbly' and I think it could be the sizings of the inside circle, but I'm just too close to it to properly see. I've only got 6 frames to work with and I'm pushing it with that, so unfortunately I can't add any more frames.

Anyway, hopefully someone can see why it just doesn't seem to 'flow'.

Thanks.

Tweak the angles of your wobbly circle a bit until it looks right 

Either that or add more frames inbetween. Your jitteryness might be caused by the sudden jumps between circles.

You may want to drop the rotation or make it smoother by having it turn 45 degrees each frame.

I'll check that out, thanks. The circle's in the middle should be 90 degrees rotation anyway, but I'll have another look. Of course, it could be the sizing of the middle circle...another thing to possibly tweak.
I would love more frames but I've no more left to play with.

This might be the key - rather than rotating 90 I'll try the 45.
Cheers.

Ok, modified version. Looks better but I think I do need to address the inner circle sizing.
