I think there are some cultural differences that prevent me from fully liking your website.
On the first (Index) page, I see your name, your logo, and a bell button. In the US (or at least to me), the bell button means "call me" because the major phone service company in the US used a bell as their logo for decades. It made me hesitant to click the button, not sure if it would open my e-mail client or do something weird.
Your logo is very organic and sketchy, but then the navigation icons are very pixelated and amateur-looking.
I don't understand the (English) paragraph on your home page. It doesn't tell me anything about you or your work. (FYI, "beginning" is misspelled on the 7th line from the bottom.)
I think the checkerboard graphic on the bottom is distracting and kind of hurts my eyes.
Your portfolio work is lovely, though. There is a lot of life, color, and vibrancy, but your website isn't reflecting that.
What I did to convert from rgb to cmyk, is I just started from zero with cmyk color mode in illustrator, in some cases colours wont change if you switch the colour mode to cmyk, but many of them do, so...
