Have used this theme for a friend, and mostly it's just right except for a page with the [contact-form] short code.
The panel(s) to type into are very similar in shade to the background, both are dark, and on my laptop screen they really don't show up well. They are better but not good on my calibrated Eizo monitor. If this theme could be tweaked to make that colour a lot paler that would greatly improve that feature of it IMHO.
