Yes, I got a tablet for Christmas, and only now have I had enough time to sit down with it, and play around with it. I'm going to end up sketching the occasional thing, as I use the new toy, and try to improve my drawing skills. I haven't done Art for... oh, six years, so I'm pretty out of practice, and I wasn't that good at anything organic (I was a pretty good technical drawer). Therefore, I'm going to be using this thread as a repository for various 40k images, hopefully for criticimsm and suggestions for how I can improve.
Thus, the following image;

Yeah, I'm new at this. It shows. I'm using GIMP as my program, and a Bamboo MTE-450E to actually draw. This is just a rough sketch of a soldier of the Pentexian Second (
Pentex, recruited from the Cthonic Guard (the underground regiments). They got a quite strong Gears of War theme, what with the fighting of pale skinned mutants in extensive tunnel networks, and, yes, there might quite well be chainsword bayonets. Hence, the heavy armour (because the Eusorgan are considerably stronger than base humans), and air supply to the helmet, to prevent reactions to Eusorgan pheromone and the effects of low oxygen.
I started by sketching the human body as a selection of ovals, in black ten to 10% opacity. I am using different layers, by the way, it's just that I wanted to show you it all, including the underlines, for comments on how I can improve. The clothes were then drawn over the top, to fit the body, in red in 20% opacity. Things were then affirmed, in 75% opacity black, for the final shapes. Armour is bluish grey, at about 50%, the head plate is white, and the eyes are a highlighted sequence of blues.
And I really can't draw hands.
