Brilliant, I knew I could count on you giving me sound advice!
BTW the font to use is Helvetica.
I was wondering about the font, it now looks a lot better. But, the combination of -> that is used has lost its perspective with the font change.
I would suggest you use a subtle amount of drop shadow on the images and text - like this, but blue (obviously);
Yes that post icon is a toughy, looks like you got that spot on! I'll try some drop shadow, and add a stronger shade of blue.
The folders are better at 19px x 13px as you can get slightly bigger/better dots, etc.. on;
Good idea, the icons feel a bit too small, though I didn't think the Invision Board used dots. I maybe wrong.
Cheers Daz, much appreciated.
