ehey~ i went once into ya website when I started hanging around this section. Itz one monotone website i can say... I'm not sure watz the trend nowadays but I do save some shockwave files of european designers (sumwhere in my pc

). compared to them, lyk i said, theirs' are multitones, n yours monotone. and they use very heavy music to make it catchy, n yours, realy mild sound..
but I'm not into soundFX since I failed miserable in making a flash website. ahahaha (bad history..) Thus, I wud suggest u juz use a normal "click" soundfx for ya buttons.. and since u r indeed into graphic design, juz lyk etsuko said, dumping in ya BEST design into ya portfolio section is one nice move. and if u r into a lot of designs, sucs as web, artistic, blablabla, u can juz divide ya portfolio into multiple sections..

. and s a designer's website, i seriously think dat u hafta play wif colors...
juz my 2 cents...
