First of all, your 1 hour job looks great than how it should look for standard designers.
Here's my review:
1. The logo
looks misplaced imo, but yeah a design is a design. Doesn't necessarily need to follow all the rules.
2. Search button, should be refined a bit and should have a label on it.

3. The over all look and feel is a bit dull, as you worked with just two colors,
making this look way different. Perhaps, use those colors elsewhere aswell?
Everything else looks fine, and would be able to review it thoroughly if we are to see it online.
