The art style is a little off-putting. If I could put a pin on why it's because there's different levels of detail on different elements. It's clashing a bit. My guess is you're doing a CG render with a photoshop paint over - you're allowing a ton of details to come through from the render (shading, sculpting imperfections, even a reflection of the armor on the cheek) but the paint over (hair, ear) is a very illustrative style (flat, no noise, only hand-painted gradients). I would either push to have more detail in the paint over, or take steps to reduce detail from the CG render. This could be done with a toon shader, or by painting over more of the render. The irises of the eyes in particular are off-putting from the clash.
For positives, I think you've sculpted a very emotive face. I like the expression, it sets a fun inviting tone.
Also, please factor into this feedback that I'm not an artist myself and disliking the art style is at least part personal preference.
