Well the first one looks like its either drunk or has been on something else
Photo wise though I quite like it - not sure on the crop though but you appear to have caught great focus and the colour (for what I know about lizards - very little) seems accurate to what I'd expect. Has nice DoF and considering everything in the shot is green, this still does not spoil the shot
Dont really care for the second shot to be honest.
Nice first though
