Very cute! It reminds me a bit of Satoshi Urushihara-sensei's work, I think that's because it's the sexy elf chick wearing a space suit. I definetly love the outfit. Her expression is really cute! Hmm, my only critique is that the image is really small. Try drawing larger next time... and color is ALWAYS awesome. But the wrinkles (especially around her boobs) are very well done, so kudos to you!
