Reminds me a bit of DiTerzelli as well as several of the artists that have been commissioned to work on Magic's two most recent blocks - Shadowmoor and Lorwyn. Your control of light is very strong, anatomy less so. This is an area you can improve on - it's particularly noticable in the de la tor study.
Overall your compositions seem overly busy - it's hard to find a point of focus in many of them. One way to address this is to push you lighting contrasts further - this is a strength you have and it can be a tool to guide the eye to the piece's focal point.
