Hercules -vs- Lernaean Hydra Picture

Yeah, this was the part of the project I had to do for Summer School a couple weeks ago.
(Yes, I have Summer School. please don't judge me.)

We were all assigned the different Labors of Hercules, (or Heracles, depending which you prefer)
My group was assigned 'The Slaying of the Lernaean Hydra".
Luckily, my Mom practically FED ME Greek and Roman mythology as a kid. . . So. . . I didn't even have to study them. HAH. Take that. . .
Anyway, I was the only one who could draw, so I took over this part.

NOW COMMENTS ON THE PICTURE:

1.) I SUCK at drawing backgrounds. I FAIL SO HARD.

2.) I tried drawing my own version of a Hydra. It looks like a dragon. . . Goddammit.

3.) I'm really bad at drawing Burly Macho Men. . . Sorry.

4.) I know Hercules dresses nothing like that, But I couldn't draw the Nemean Lion skin.

5.) I fail at drawing armor.

6.) I've never drawn a Crab before. . . Huh.

7.) I was too lazy to draw Iolaus. . . In fact, I was generally very lazy with most of the things in this picture.

8.) This picture generally fails. I do like how the main Hydra head, Hercules' face, the tree closest to Hercules, and the Crab turned out. (I forget its name.)

9.) THIS PICTURE IS EXTREMELY BLURRY. GADDAMN. :I

So. . . yeah. There you have it.
