These are awesome. I must say, those waterfalls are beautiful. And those animals are awesome. I've never seen
them before. The snakes sure seem friendly. A far cry from Australia where anything tries to kill you, haha. Seriously nice waterfalls though. I'd like to visit that place some time in the future if I ever have the opportunity.
You're not too shabby at taking photos. I think some of these shots are composed quite well, so while having a better camera would enhance the quality and allow you to do more professional looking things, these still look very nice. At the end of the day the talent is what will shine through. You take better pictures than lots of people who think the equipment is everything, at the very least. :)
