Branding - Kreuzer Baumpflege

My client Matthias Kreuzer founded Baumpflege Kreuzer and asked me to create the companies face / whole branding and online identity starting from logo, business cards, stationary to the finished website online. Please take some time to look through my project (https://seabee.at/work/kreuzer-baumpflege), feedback is highly appreciated :) since I spend quite some time on it ;)

I guess the logo makes sense only in german, this is why I better explain:
"Kreuzer" is the companies name which means in german "Cross", the addition "Baumpflege" means "tree care" thus the symbol in the logo has the shape of a cross and/also the shape of a plus (for care) - then I added some detail to make this symbol also look like a leaf at the same time (to see straight away what the company is about) So what do you think?
