バック流れるグルーブに乗って、楽しいフレーズを弾くという、音ゲーの基本を理解してくれないと、演奏して楽しくなるはずがありません。

This BMS is worse than the BMSs you made before.
BPM is not matched between background music "BOYS" and BMS.
And assigned sounds are not interesting.

About your music sence:

first, bass drum does not match the phrase of "bad boy".
Second, many percussions does not match that phrase.
Morevoer(third), if you want to make a genuine "original music",
please do not famous singer's music phrase.

About your Back Ground Animation sence:

First, all BGA's should be decreased from full-color to 256.
Because it is comfort for us to download files.
Second, you should search and use many fonts which is exbited at internet.
For having many fonts enable you to make cool BGA's.
Otherwise, you should use many graphic application trials(i.e. paint shop pro,Adobe's photoshop and e.t.c.) so that these are free!
(the best free apprication is able to use Adobe's photoshop plug-ins.for having many plug-in enable you to make cool BGA's. Althogh this applicaion I know, but I don't know where it is...sorry)

You know, Japanese bms music are so high quality. (but,government security is so cheep :-< ) and your making skills are still unripe. Please listen to more leading Japanese high-quality music and learn from it. Someday, you can grow and become leading bms musician.

You arranged "boys"?
As far as I listened,boys' phrase is few.
And,rhythm get out of tune...

うーん、通じるかなあ……？

Sorry, I cannot understand English...
So, I'll down in Japanese.

だいぶ良くなってきてると思います。
ボーイズをテクノにしようとしたその発想は流石といいますか…
もっと精進してください。

なるほど、Boys・・・スマイルですか・・・（謎）
最初「うお〜、スゲ〜」とか思ったんですが
Boysをフィーチャーしてるんですなぁ・・・。
上手く考えたとは思いますがやはりキー音はショボイです。
でもミニマルと言われればミニマルなのかな・・・。
うぅむ・・・ただのテクノな気が・・・Σ（￣∇￣：
