Okay... the first picture. I don't know how much you intentionally watered down the colors and blurred the photograph, but it was done well, and is a good idea for combining a photograph with a drawing. But mixing photos with drawings is never easy, and the black lines in the dark character's cloak kinda trips up the effect for me. And his pose seems a little unnatural. His knees shouldn't be on the opposite sides of the picture. Okay, I'll say it. It looks like he's trying to bust a walnut with his ass.
That's kinda harsh, and I'm sorry about that, but you really have some good things going on here, and I think it deserves more of a response than "Gee, that's nice. Next picture."
There's some problems with the elf girl too. For starters, her chest looks a little lopsided.

I think it's the shading on the cloth, which overall is done well, but the point of tension for the folds is a little off. No other way than to be a little blunt about it. If she's built like that, then the point of tension in the cloth should be near her nipple. And I have a problem with her hands, too. They look like they were taken from a Barbie doll. Of course, I know as well as anyone that hands can be a real pain to draw.
But overall, the first picture has good atmosphere and design, and believe me, that is a lot more elusive than a few piddly little anatomy problems.
As far as the second picture goes, my one problem is that it was a little too blurry... took me a minute to figure it out. But once I did, I got a kick out of it. He's just giving them hell isn't he? Too many people just do "Here's my character and here's his pose." "Grunt." Nice to see a little action.
At any rate, keep them coming! I wouldn't have been hard on you if I thought it would be a waste of both of our times.
