A comfortable heel

These are the shoes I wore for my interview the other day, they are from Next and have a delightfully comfortable heel. I usually wear a heel like this or a small wedge to interviews, you have to be comfortable in what you are wearing otherwise you wont be able to relax and that is a key factor when dressing for an interview. 
What do you think of the watermark ? I don’t like using a watermark really but have decided it’s a must due to the amount of photos I put onto the internet. I decided to just use the Prettygreentea website for these, maybe I will use my name or create a logo for the blog and use that. I haven’t decided yet, one thing I wont be doing is putting a big ugly watermark across the photography, it spoils it and my photography is for people to enjoy. 
Do you use a watermark on your photographs?
