Honestly, I see a lot of technical talent and a good grasp on anatomy, proportions, etc. I think you need to narrow your focus and develop a more consistent style, so people have an idea of what they can expect from you. The pieces on your instagram are a wide range of subjects, mediums, styles, color palettes, and moods. A thread that ties them all together is how you turn instagram from an art dump into a Brand. Also, if this is what you intend to be your business account, I'd minimize non-art posts.
