@Zemlon Thank you for your kind words! Your gallery is a good start, keep going. Try to find new and interesting ways to light your scene, compose your shots, and learn to modify & understand the technical aspects of shaders, render settings, lighting, etc. That's what really helped me get better. And once I stopped thinking about the NSFW aspect of my art and started concentrating on how my art stood on its own, once I started thinking about what I actually wanted to convey, my renders took on a whole new dimension. Of course, these are just the best ones in my opinion; I have works I'm not as proud of. I hold them in such high regard because I learned important technical skills doing these renders. Magical Girl taught me how to use a fluid simulator. In Specialized Task Force, I learned how to do custom glowing tattoos.
It's all a learning process; keep it up!
