I'm not a fan of NSFW art, but the anatomy looks really good, which usually is a must for NSFW art to feel "pretty to look at" and not uncanny, so celebrate that! I would work on shadows and lighting, specially on the face area since it looks flat. On the right underarm, and between the breasts, you drew a shadow that really helps create shape and 3D volume, and that's what you should aim for. You should definitely work on your game ideas ASAP because a lot of people would love to see more of you art as it already is, you'll have plenty of time to improve as you go!
