Hi There!
Its not too bad, your being too harsh on yourself :) But we can do a little bit of magic to improve some areas of it. First up we would want to work on the colour and branding - it looks like you have aimed for the cadbury purple but it seems to be coming off as pink, which is sort of dominating the page, so we should look at adjusting the colours, make your logo more prominent and photoshop your images a bit as well to make them little bit more professional. Then, as shopify plugs directly into Facebook, I think we should take those changes and apply them to the Facebook page. We need to update the Facebook banner so that your profile pic is not covering up the logo, maybe get another thousand likes so that you will trend higher, we should look at doing some sponsored advertising through Facebook as well.
We can do everything listed above, (and a lot more!), but what is listed above will take about a week, please let me know any thoughts!
