Item Review-Web Elements

Can someone give me any feedback on my navigation headers. Not sure on the pattern or the colour, any advice would be helpful

in terms of colours there is not really so much to look at, but the orange and green looks fine to me.

What I do notice that the alignment seems to be of a little. On the green version the links and the search box does not seem to be align vertically right in the centre. Also the magnifying glass button seems to be nudged down a few pixels.

The green version could maybe also do with a little lighting and shading as it looks a bit flat.

Otherwise, good start, but you will need to add more substance and options for a complete item.

Hope this helps
