i've had plenty of opportunities to catch a sandile while enroute to glitter cave and back to Amberette city (i think). i kept knocking them out on accident though. plus i wanted a helioptile more and i had but one net ball in my possession and alot of good it would have done. sarcasm intended with that last bit.
I hope you use this type of color application more often in your artwork. Combined with the uniqueness of Krookodile's design as earlier pointed out by yourself, it gives off quite an appealing visual flavor. Very well done on capturing the greatness of this Pokemon in action.
There I was, browsing my devWATCH messages while eating, and then I spotted this lurking within it's depths. With a swift click, I arrived at the epic deviation page... and here I am, eating Cap'n Crunch cereal. Is that odd? XD
