I've been painting creatures and characters for a while (you can see at my Artstation to get a grasp of where I am skill-wise) but I want to try something new, explore, and branch into environments. This means a lot of new topics, but that also includes old topics that I need to better understand like lighting and composition. I love environment concepts from artists such as Feng Zhu's natural pieces like this:
