I've continued making drawings for the mod for the last two weeks. I've been trying to do more full body drawings to get the hang of drawing correct anatomy and proportions. The above picture is part of a questline I'm currently writing. Meandraco was right when he said that writing is probably the hardest part of making game content. I've not written in many years, so I'm approaching this at its own pace. Some days I'll only manage to put in 100-200 words, other days several hundred. There are some really neat tutorials and tips about writing that I've found here such as this:

A really good, comprehensive tutorial and collection on writing by helixthefallen

If you are also someone who wants to get into writing, I can definitely recommend giving them a read.
So far, I am about shy of 3000 words in. Maybe I'll post the mod script once it's in a more advanced state.
