Hehe, no worries - I had to ask as sometimes I come across as being a bit too direct.
As for the first point: The colour palette you're using doesn't seem to complement one another (you're using conflicting colours). For example, on the home page alone we've got Black, white, grey, three different shades of blue, red, yellow and orange with mixed saturations as well.
Padding is seen as the space between an element and its container. As a practical example of inconsistent padding: look at the psace between your search bar on the top and left hand sides as compared to the bottom and right hand sides - it's not even. Now this is present for just about every element on your site: between sidebar/main content, top nav / call-to-action buttons, between sidebar reg. buttons, copryright / disclaimer section in the footer.
Another problem is that your registration and login buttons have a different radius applied to each one: making their rounded corners odd-shaped. The "Submit your CV for Free" text is also too large for the button background as it almost overflow it entirely (which is another padding problem).
Hope it helps. There's a few guides on
