Welcome to the wonderful world of the Mayhem. Judging by your first four images, your going to have a fun and spectacular future in model photography. They're very good work. Make yourself right at home and enjoy the ride!
OP, you've described yourself as a newbie so I feel safe to say that this is a typical 'newbie' mistake.
a) watermarks, especially like this ruin a photo
b) nobody will take you seriously with this all over your photos
c) are you really expecting people to 'steal' your images, and if so what for?
Anything you post on the internet is liable to be stolen/misused etc. Learn to embrace it and do what I do - view images you post online as free sample giveaways intended to get you noticed rather than precious jewels you need to protect at all costs.
I don't watermark my online images at all, and I have a tumblr where I positively encourage people to reblog (some would say 'steal') my work. I pretty much don't care what happens to then as long as they get me noticed.
Sure, put a big watermark on proofs you're sending to clients who you need to sell retouched final images to but honestly, nobody will take you seriously (even here on MM) if you don't remove them from your portfolio images.

Wow! I have thousands of images I never posted because of guarding them like "precious jewels" that I didn't want stolen online. I probably cost myself a ton of potential work by hoarding them. Thanks for the perspective shift. :^)
