Whoooaaaaaaa, you are seriously good. There's not a lot of time left if things are to be ready by tomorrow evening, but if it's possible then it's possible. Can you shoot me any examples of the style you'd be shooting for with the doodles? Ideally I'd want something that could match the original illustrator pretty closely, just as far as the shape and features of things. No worries on technique.
From what I saw in your gallery it seems like you would be an ideal fit for the final ending picture described in my original post. For your convenience, here is the entire "ask" description in one place:
Sketches: • The white tiger is pouncing at the “skull" pirate , like she’s about to murder and then eat him. She looks pretty scary! • The gray kitten is looking on with enthusiastic approval. • Optional background (only if you think it would look good): The gardens, a with trees, bushes, grass, fallen pine needles, flowers and some pavement. • In this illustration, the situation is that the “skull” pirate has lead a tigress (under death threats) to the “shark” pirate, and now we see the skull pirate is looking sheepish and full of excusees, embarrassed to see the shark pirate, but the shark pirate is exasperated, terrified, flustered, and pointing at the skull pirate like “you brought a tiger?!”. • The skull pirate is sheepish and full of excusees, embarrassed to see the shark pirate. • The shark pirate is exasperated, terrified, flustered, and really 'dressing down’ or ‘chewing out’ the skull pirate, as if he were saying “you brought a tiger?!" • The tigress is quietly behind Skullzy, being all cool and scary.
Full-colored idea: • Definitely sketch this out very lightly and quickly first, as it may take a few tries to get the positions correct. • This is the happy ending closing shot at the end of the book, and it’s everyone from the story asleep in a bed. Specific positions are described in the link below. The humans are asleep under the covers, the white tiger is at the bottom of the bed asleep with the gray kitten, the two pirates are passed out and cuddling wherever looks right (I trust your creative judgement since I have none), and there are two cats, a black cat and a three-legged calico cat, asleep in the bed as well. You can draw the bed from whatever angle you think would work best, but it would probably be a good idea to make the bedframe and external details kind of abstract or just not there. The focus should be on the sleepers, and the viewer should be able to tell they are in bed, but not be caught up trying to figure out why the bed has a wall on one side, etc. References for everything are in the three albums below.

They are about as big as cupcakes, or perhaps at the most as big as a very small dog: http://imgur.com/j2IrYlz • The black cat and three-legged calico cat, the two sleeping humans, the bed, and all their positions (including specific instructions): http://imgur.com/a/wqCM0
