I absolutely love the ghost with the most. I like the orc. In terms of any constructive criticism that I can offer… even if this is a creature that isn’t human, some anatomical aspects should be kept in mind. Like the calf muscles, the inner gastrocnemius muscle should be lower than the outer one. Same thing goes with your thigh muscles, they seem to be even in terms of height. The vastus lateralis (the outer one) is usually smaller and higher than the vastus medialis (the inner one). Just some anatomical tidbits that can help you build even better models. Whatever helps. Regards.
