Subtle curves come back

After a long time of a very square/rectangular look to my website, I have brought back subtle curves here and there across the website. These curves are designed to make things like buttons more obvious as well as add to separation. There has been a lot of exploration around what suits it and what doesn't but I think the changes I have made are very clean and follow design techniques of today.

For example, input boxes and windows now have curves. You may have also noticed that I have introduced a new quick alert to the site as well as the newest version of BalfPick.

I'm aiming to make my design a combination of curved buttons and elements built on a flat design and think I've done it well so far.
