Hmm, your links are black, Post titles are black , everything is black.
You need to get some contrast involved, make your post titles stand out, make your links move visible and perhaps give a different background for the posts and the sidebar. Make use of free icons, or create you’re own for things like your twitter widget, give it a bit more life.
I know your only 13, but if your going to have a portfolio to show and impress potental employers, other designers, etc you should keep it professional.
(i.e. Keep your unsuitable youtube videos some where else for your friends to see, such as bebo, facebook etc)
I think the grey and black works pretty well to be honest. For a 13 year old, you’re pretty good at this. Well, you’re doing better than I am and I’m 27 (although I’ve only been doing this for about 3 months).
From a design point of view, you should look at getting a little more colour into the site and maybe a few graphics to really make it pop.
:P Might agree with that in 5 years… We’ll see. Got some new plugins. Can you help me and anyone who has a Mac, download the iPhone SDK and take a screen shot so I can see what my site looks like because I have a new plugin that give my site a new look in iPhone type enviroment! Thanks!
