Been working on my new skin (based on Eric's awesome skin) and there is a few parts am still unsure on
If you have a few mins free take a look and the images below as there are a few "arrows" with questions on them...
It looks great! I love that bar at the top and I think it will look better without the bottom breadcrumb. You can also try and change the color of the top breadcrumb to black like the bar on top. If you dont remove the bottom breadcrumb I'd say it would look nicer if black as well.
1st example I prefer the simplicity, but I am not fond of the green, if you are going this way, then use a more yellow based "natural" green, like those on the left of the banner image, not those on the right of the banner image, and the green you have currently which is a particularity unpleasant fake green colour.
Don't lose the bottom breadcrumb from the whole board, to remove it from the front page is OK, but not altogether, it performs a vital function in being able to easily navigate your site from posts or thread view.... restyle it to be less intrusive if the look of it offends, but never remove it I cannot navigate forums other than Xenforo now, or rather it annoys the HECK out of me to have to scroll to the top to navigate, the bottom breadcrumb is brilliant!
Where's the logo? I think I prefer your current skin, which has a lot of black in it. And for all the melons...perhaps have a little Anime girl (cartoony style like in your current logo) taking a bite out of a piece of melon.
