Mel I like them all. It's hard to pick a favorite! Each one has it's own merits.
The first has excellent shading and highlights.
The second is very cool in color.
The third is got to be the coolest and most badass. I love the expression like "don't piss me off" or "you haven't got a chance".
I'm the VERY proud owner of that 3rd one. It came to me as a surprise from the mods of the Lair during a horrible time I had last November with some surgeries to my right lung. Here's cutestsandgirl presenting the airbrushed painting to me in my post-surgery critical care room.
I got literally choked up when she pulled that painting out of the box and I saw how much people I've never even met before (like Mel) were so supportive of me in this online community of friends we've made in our home called The Hunter's Lair.
