I'm currently in the process of making a design for a web application.
Although I'm very interested in design, I'm actually a programmer, and I don't have a lot of experience with design. That's why I came here.
I have the following set up:
(click for original)
The menu on the left has a small hover effect, where the text turns white and gets a very light gray-ish background color.
I tried my best with the limited knowledge I have, but I just have the feeling something isn't right (and it feels too plain).. I paid special attention so that everything is in an "invisible grid" (e.g. there is a line flowing down from the logo to the left menu-bar).
I also tried my best to match the colors (the red and green are required by the customer). But I'm having trouble matching colors with the green..
Could you provide me with tips (any tips IMHO that would benefit the design)? I'm willing to upload the css and html if required!
Thanks for the help :)
UPDATE: This is what it looks like now:
