Maybe a citrus leatherback. From that pic, he looks like hes got the solid black eyes too which would make him a translucent as well. It's hard to really judge a color of a young dragon cause they will change colors as they mature. Best bet is to look at the parents to give you an idea.
As to the OP, in that first picture of the leatherback, he needs to fatten up a lot. His tail is pretty scrawny looking at the base and in that picture of him on your hand, it looks like the fat pads behind his eyes are sunken in. Not a good sign. That normal one in your second post though looks pretty good weight wise. I do like the color of that leatherback.
