Flat colors

So... This is how the scene potentially looks finished. No shades or further rendering. Why? Well, as usual, try to save time. I'm personally very much into flat colors. But I wonder what you guys think about it. Would you rather have a full render at the cost of roughly more time, or are you ok with flat colors? 

Also, sorry for the lack of updates. Still IRL stuff I'm taking care of it, but the content is NOT stopping from being done. It's just taking time to be released, and that's totally on me. Sorry about that, guys.
