Indeed within this section "Showcase Your Website" you can provide a link to your own website without violating the self promotion forum rule (which applies to other areas)... We're all ready to help with reviewing your website ;-)
I've had a look via searching on G... and see that you are using vBulletin... Which is a good platform to use... colour, layout etc looks okay - for me forums are pretty much standard stuff given common use of platforms... I think the important thing is engagement of users - and that looks like its heading in the right direction...
For the first time visiting your forum, it redirected me to forum/activity.php which I suggest you change it to forum/forum.php
An important point is you missed heading tags on your forum template, it will be difficult for you to get good rankings on search engine results. And some other points relate to On-page SEO you will need to learn here or somewhere.
