It lacks flow...or proper looking proportions....or both. If you are going to stick with the wonky proportions you currently have, at the very least, make it a bit more dynamic. Your last piece suffered this too--it's far too stiff; the neck feels kinked and unnatural, the head seems uncomfortably tilted, the shoulders are at near perfect right angles, and the rest of the body seems...tired...and poofy, as if they were pillows or something. It can't be stressed enough: you need to study real life more often.
BUT, this is good that you are pushing yourself to go big, just hope that you refine as much as you would a small sprite....
The colors right now, just aren't doing it for me. I think they are rather bland, have fun and experiment a bit
not all alien monsters are lime green. But that's personal preference I guess.
Anyways, good luck.
