I had a really hard time drawing men when I first started out. With women, it was easy- just look in the mirror. But guys? Not so much. My best suggestion is to look at photographs of men and draw what you see. Pay attention to the jaw lines, the way their hips differ in shape from ladies. Men (especially comic men) are more hard angles. Their top halfs basically look like up-side-down triangles. Don’t worry about style- accuracy is more important. Style comes after you figure out how to put everything together. If something is tripping you up, you need to draw it even more. I know that’s sort of annoying but it’s the only way to get better. Find some photographs of handsome muscular dudes and start sketching.

Kinda depends on what, exactly, you’re trying to do with the program. Since you’re asking me I’m going to venture a guess you’re a comics person too? If you want to know my basic process, I start on paper. 11 x 17 comic paper. If you hate erasing you can use blue pencil lead. I kinda rotate. Draw up your page. I ink with a pentel brush pen. Panels are usually done with sharpie since I want the lines to be solid and straight. I have a large format scanner (it was about 200 bucks). It saves me from having to either a) scan my pages in pieces or b) draw on under-sized comic paper. 

Once you get your scan, I suggest you clean it up a bit in Photoshop. I play around with the brightness and contrast so my dark lines are darker. Save it and pop into Illustrator. All my ink lines are vector traced. Open a canvas and do file—>place. From there it’s literally just the image–>trace option with ‘ignore white’ selected. This gives you just the black lines. If they look good to you you can just select them all and then drop them back into a canvas in Photoshop. My stuff is 350 DPI. It will import it as a vector which you can’t edit unless you decide to rasterize. Then it’s just building up layers behind your drawing for the colours. I generally do just the flats on one layer. Darks on another. Lights on another. If there’s weird effects (like when I draw Chamber’s glowing veins) they get their own layer too. Word balloons are the top layer. I shove all text in a folder because it can absolutely get out of hand if you don’t. 

That’s the bare bones process for me.

I basically taught myself over the course of many, many years. You sorta pick things up here and there from kind souls that write free tutorials. If you’re looking for something structured, lynda.com has tutorials for basically any program you can think of. They are a pay site though. 

I have 2 wacom tablets. I use a Intuos at home and I have a wacom Bamboo at work. Honestly, I don’t use them so much for drawing as I do for colours. I don’t draw super well with a tablet! The majority of the drawings you see are ink and pencil on paper with colours done either in Illustrator or Photoshop.
