One of the prime focuses for the project will be the art. I've been coasting with my cartooning skills by just pencilling doodles for ages, so forcing myself to make a moderately art intensive game will give me the practice I need to improve. However, since I'm still pretty unskilled at art I'm unsure exactly how long this will take. This is a problem when you have to plan to a fixed deadline!
At the moment it takes me several hours to complete even a single character pose (or roughly two to three World Cup matches [grin]). This is partly due to unfamiliarity with what Inkscape can do, partly due to unpolished art skills. Thus I really need to practice those skills over the next month to get a good idea of exactly how much art I can put into this game. I suspect once I've decided on the basics of what characters will look like and build up a portfolio of character poses it will be much simpler to construct new images - I could just frankenstein (heh!) various body parts in different poses and stitch them up for a new image.
On that note, here's another piece of practice art:
