Hi there. Usually, we have a rule in A&D that states you must post at least three pieces of art to have a gallery/shop. However, since you're looking to improve, I'm going to let this slide. I certainly don't feel like hindering an artist who's looking to get better should be happening here. Good luck, hopefully you can get what you're looking for out of here! In fact, maybe I can help..
1.) I've always had an idea about a wolf-like quadruped that's Ice/Steel. It has a similar profile to Luxray, in that it stands strong and carries itself with pride. It would have ice protrusions coming from its shoulders, ankles, and forehead, while it's spine, tail, and neck would be adorned with a mental, filigree suit (almost falling over its back like a cape, but not flowing). Lastly, this icy mist should be emanating from it's mouth. It's a dark and mysterious creature, so make sure it's stance and expression reflect that. If you color it, the pallet should be light blue and gold.
2.) How about a simple sketch. Just realize the fakemon on paper.
3.) Name: Koldrador.
Type: Ice/Steel.
Height: 4'11
Weight: 142.2lbs
Classification: The Mist Pokemon
Flavor Text: Koldrador rules the icy mountains, often chasing the smaller Pokemon away from its territory. It stands atop the highest peak, allowing the moonlight to reflect from its metallic skin.
4.) I will not be using Koldrador for any purpose. My objective for posting this is to challenge you and give you some direction. So just so you know, this fakemon will not be appearing in any hacks, alternative art, or associated with another project. Just have fun! :)
I hope that's good enough! Let me know if you need a more detailed description. Best of luck to you!
