From knowing no knowledge of either graphics or web coding. I am going to rate you as a student learning from nothing.
As your first design this is your rate.
Template Design: 3/10
Appeal: 2/10 ( Simple design is nice and clean, but page is too dark, not centered and not interesting. )
Technique: 1/10 ( Same pattern was used all throughout page, always good to use different techniques to keep page interesting )
Flow: 0/10
Uniqueness: 0/10 ( Come up with your own style of work and use it in all your works. )
Coding Rate: 3/10
Use of code: 5/10 ( Clean, readable but could be better. So happy you used divs instead of tables. That right there is a great start already )
Uniqueness: 0/10 ( Again, come up with your own style of work graphically and add it into your work. There is a style of code as well )
Flow: 0/10 ( Flow in the code is different from the design. Flow in code is understanding where a div starts and ends without following the lines. ) Example:
<div id="div01">
<TAB><div id="div02">
<TAB></div>
</div>
Without following the line, you already know where the divs end. Good for editing purposes if your going to release templates and such.
Overall
For your first design ever. I will give you a C+ for these reasons
1) Page is not centered
2) The same pattern is used too much
3) Could have spent more time to make it better in some ways, More time was spent on code then on design.
If you really want to learn, I can teach you and give you templates to work with. They are not RO templates, they are designs I made at work for professional businesses and etc. But you can still use for learning.
