I think it looks nice so far (if a bit plain), but if you want a really minimalist look like this to work, I would suggest going with a sans serif font instead of Times.
Google Fonts has a great collection of free web fonts to choose from. Open Sans and Duru Sans are both really pretty.
Also, I have to admit, I'm not sure what each of the menu icons are for - the first one is probably "about me", the second one might be web design, but I'm not sure, I have no idea what the graphs are for (information design?) and the last one looks like it ought to be "settings" which I kinda doubt you have for a portfolio site.
