Backgrounds Limited, TM

Creating backgrounds(BGs) is definitely different on how you create sprites or cutscenes. Furthermore, you can reuse them on your future projects or at least render them. There's a lot in the internet that you can possibly use (remember to credit the one who made it) though sometimes it just doesn't fit the style of the overall theme of your visual novel. The following are great sites to rummage through:

• deviantART
• pixiv
• zerochan

Below is an outline from a real picture and given base colors:

Principal's Office in Animus Rush

Now off to giving it shade and lighting! (Look forward to seeing the final image in my devArt page soon.)
