This has been my personal graphics portfolio site for 17 years (it was my nickname in college), but will be switching to using my full name to promote my art. A short, pronouncable, fun sounding LLLL.com would be a great brand to develop.
LLLL.com are always valuable. This one is also brandable and readable. Not so good for the "booming" chinese market, because of the "oo". I think you can get from high $xxx to low $x,xxx.
I think it has more value than posted above. If you look at 4 letter names being sold at about $300-$500 reseller price that dont make any sence and not readable then this one will sell for around $5K easy.
Quad western premium + repeat "o" + pronounceable.
You will get $1000 minimum.
You could also just keep it for yourself and redirect the trafic to your new website.
