It's really good for a beginer, but you know there was this preset from usgroup1_winamp and it was really close looking to your's. You sure you didn't inspired from him?
If not, it's a good preset.
Best wishes, Florin
The preset is quite good, but you could have made some optimisations, for example, clubbing the blitter feedback and dynamic movement in the last effect list.
and one more thing, in the dm u hav ar=rand(777)/777-.777/77;
why did u choose 77? :P.
