Finished Winter 2016, Clip Studio Paint & Photoshop.
I was commissioned to draw each of the 5 Combaticons from the original Transformers in my own style. I drew them based on the appearance of the original toys. But I am a huge fan of the Combaticons as they appeared in Generation 2, with their enduringly garish neon 90's color schemes. So, once I was done with doing the illustrations the way they were supposed to be, I recolored the artwork into the G2 version and added that swirly green grid background for the proper G2 packaging feel.
You can see the original G1 versions of my artwork on my DeviantArt.
Personally, I like G2 Combaticons way more than the originals! What's better than a crew of neon death machines with purple camouflage?
