I have been planning an adventure game for so long now, yet I can`t really make proper decisions. My earlier projects teached me to set myself relatively little goals and better not think too big or too long about my projects.
However, right now I thought about using photos as backgrounds for my game. They are fast to make, but I wonder if they wouldn`t appear a little cheap - especially since I am going for a more cartoony style for the characters. Setting-wise, my games go in a very similiar direction as Kings Quest, with many fairytalish forests and fantasy landscapes to explore.
My earlier projects (around 2008) looked like this and had a huge amount of cartoon-styled animations:

My main character is a cat with a hat (the one Graham from KQ wears) and still looks like this:

(The furry thing at the bottom is a reference to that horrible horrible internet fandom that likes erotic pictures of animal cartoon characters. My character here pretty much carries two chainguns on his arms, ready to blast the one who calls him a furry - in case you don`t get it

)
But, even if those backgrounds look simple, together with the animations they took by far the longest time at this ambitious project. With photos, this process would be unnecessary and the whole game making process would speed up. And as I already said, the problem with the clashing styles will appear.
So, just for trying it out, I made this little experiment using that (actually not very pretty

) sketch from the page above:

I actually kinda like how the character in all its black and white glory contrasts with the surrounding. I think it almost has some kind of charme to it. If I animate him nicely and let the scenery cast shadows on him at the right places, it would look kinda nice.
It would be very awesome if you guys here could give me some advice on this.

Or, do you know any other games where something similiar was pulled off right?
