Hmm if that is your first page ever made it's not so bad but I think it looks like pages from 10 years ago no offence. If you are planing on even selling this domain it should be more bright and more professional. For promotions there is a lot of options:
1. Google advertising campaigns
2. Listing your domain in directories
3. Link exchange
4. Paying for banners or links to be displayed on highly visited pages
Hope this helps you. And good luck with sell
Hm just saw that there is link to main page ( to much space between it's collectors item image and then link to main page ). I would redo index page or maybe even delete it so it would open main site just my oppinion.
