Third is pretty spot on for what I would recognise in a frog, so well done with that.
Fourth is definitely one to continue with, when you get the chance to do so.
And the fifth is looking rather spectacular, but once again, lacks that final bit of detail that could be obtained through shading or cross-hatching, even.
