When you reply, there's no images for Bold, Italic etc, but the words are visible. The clickable smilies background is white, where it could be better another colour, imo. The forum options don't work yet. The colour of the bar between each post (lightblue) would better be another colour, more blueness at the bottom of each topic, with the forum name in white makes it hard to read. You need a couple of more icons, such as for a password protected forum. The background behind things like "Delete cookies set by this board · Mark all posts as read" needs to be changed. The background behind forum notes has the right colour but has a white bar around it (don't know if that's intentionally or not, I just noticed it).
Just a couple of things I noticed. I must say the skin is coming along nicely. Nice buttons.
Oh and you can't use Quick Edit
