Replying to Shameless Self Promotion

So guys, got some of my pictures up from my trip to Kenya over Christmas.

Please let me know what you think, any criticisms, what i could've done better etc, let me know!!!

Also, is it worth properly watermarking them, like covering half of the image with a semi-transparent name?

Thanks!

(Also if it makes it an incentive, +K to any good criticism! haha)
