OUIL505 - Thumbnail development

I liked the potential that the thumbnail of Gregor peeking out the door had - it was both disturbing but also a bit silly, having him stood upright like that. I feel like this is a good reflection of the often ridiculous style of writing the story possesses with its bluntness, so I developed it into a bit of a rougher sketch:

 I then developed it further on the computer, redrawing the door to make it more solid and also adding colour:

I went for a limited colour palette since I don't feel confident enough to use a full one at this stage.
I'm not pleased with this image because it doesn't feel 'tight' enough as a composition - I suspect it's because of the perspective of Gregor's parents' heads which doesn't make a lot of sense and makes the rest of the arrangement fall flat. I will continue trying to re-work this.
