Maybe you should focus more on the details. To be honest, take this theme as part of your learning process, start a new one..I’m not saying it’s terrible, but I don’t think it’s really “fixable”. Maybe next time try to spend more time on photoshop before going to code.
Didn’t click in every link on your page, but there are some things that works weird, like when you click on the slider and it opens the jpg img only.. another think, I don’t think it’s a must, but I like when there is indication for drop down links on the menu..
Don’t give up..Good luck
